Magnifying Glass

Transcript: Production Of Heat The suns light energy enters the convex lens and is refracted since the glass is more dense than air. The lens then concentrates the light into one small point, the focal point. When all the light rays all meet at this point they create heat. Creating An Image Convex Lens How It Works A magnifying glass is used to magnify (enlarge) an object its assists people with hobbies and crafts and also helps people with low vision, and other vision conditions. convex lenses or magnifying glasses can also be used in solar panels. Convex lenses are usually made of glass or plastic, which is used to refract the light rays to a concentrated point. The lenses are often double lenses meaning that there are two curved sides. Convex lenses are curved outward. How Its Used Light beams from the top of the image travel through different parts of the lens. The lens then bends the rays through refraction, since the glass is more dense than air. To the person looking through the lens it appears as though the light beams come from a point that is further to the left and to the top. That is a virtual image because all the convex lens has done is bend the light rays in a way that creates a virtual larger image. As the lens bends the light rays we can not see the real image, we can only see the virtual magnified version created. Magnifying Glass

Transcript: Did you know that Rodger Bacon invented the magnifying glass!? What is a Magnifying Glass used for???? I don't mind an interview at all!! Rodger Bacon testing out his magnifying glass. How do you get used to these type of things? Well you know it is what it is and these things are helpful to other people such as my owner. What do you do for a living? When and why was the magnifying glass invented? Magnifying Glass I see. How does it effect you in certain ways? Scientists traced the very first magnifying glass back to 1250. The magnifying glass was invented because Bacon thought it would help people see better. Why was the Magnifying Glass invented?? My interview with a magnifying glass By: Sache Marks Well the thing is, I help people solve mysteries, you know crimes and stuff like that. A magnifying glass is used for looking at things up close. You can relate this to a microscope. A magnifying glass is used for many things, Such as: looking at insects, looking at words closer, and maybe for looking at chemicals up closely. The magnifying glass was invented to be used for many things. It was invented to produce a magnified image or object!!

Transcript: Presented by PERSON for COMPANY Magnifying Glass What is the purpose? The magnifying glass is and object that uses convex lenses that is used to produce amplafyied images of other things, such as words. What is the purpose? How it evolved How it evolved Magnifying glasses have changed in many ways such as there shape, size and color. The creator of the magnifying glass was a person named Roger Bacon. Roger created the object in the 13-centry england. How it works How it works When light is passing through the convex lens of the magnifying glass the glass bends rays of light so they create zoomed in images on your eyes. Facts... Facts... Most magnifying glasses use double convex lenses to make things look bigger. Many people use magnifying glasses and sun light to set other objects a fire. You can get the best focus and highest magnifying power by putting the lens closer to the eyes. The lens and eyes should be moved together. 1 main posssible way to use the magnifying glass is to survive postion the glass up to the sun and the sun magnifys its heat as the rays pass through making the rays 10 times as affective good for survival Possible ways to use the magnifying glass Possible ways to use the magnifying glass

Transcript: The simple lens of the magnifying glass is using the retina and lens of your eye to create a virtual image, that appears to be closer to the convex lens of the magnifying glass Modern magnifying glasses are double-convex lenses and they make the objects appear larger. The lens is convex on both sides, ie. thicker in the middle. When viewing objects the light rays are bent towards the center of the lens, making the object look larger than it is to the eye Each magnifying glass has a focal length, which is the distances from the optical center of the lens to the point where the light rays converge History of Magnification During the 16th century, the first primitive microscopes were invented using multiple lenses HOW DOES MAGNIFYING G S WORK? LAS If you look through the lens at the object, you'll see an image that is right-side up and larger than the original The Egyptians had discovered an almost clear crystal, called obsidian that was used to view small objects Historians seem to agree that the Romans were the first to discover glass in the first century AD

Transcript: Magnifying Glass March 4, 2019 by: Purity.O.Ogbeide Demarcus Preston Ezequiel Nava Hi sisters ... ABOUT A Magnifying glass: Created by Roger Bacon in 1201-1300 Most magnifying glasses are double convex lenses. A magnified image is a called a virtual image. it is used to make an image bigger, it can also be used as a last resort to make a fire. This is the ancestor of a compound microscope. ( normally found in a lab) A compound microscope A Compound Microscope Uses multiple lenses to enlarge the image of a sample. A compound microscope is used for viewing samples at high magnification LENS Convex lenses A lens surface that bulges outwards is called a convex lens. Identified by their shape which is thick across the middle and thin around the edges which are curved outwards. Since the surface is curved, different rays of light refract to different degrees; the outermost rays will refract the most Objects That Use Convex Lenses Telescopes Binoculars Magnifying Glasses RAY DIAGRAM This is the ray diagram for a magnifying glass.

Transcript: if you had the ability to change this product in anyway what would you change? How was it used when originally invented ? Some ways the magnifying glass has impacted society in a negative way would be effecting the eye sight. Magnifying Glass Environmental by: Malerie Ramirez Hector Pena Juan Cisneros Raul Esquivel Some ways the magnifying glass has impacted society in a positive way would be that it allows you the see things that the naked eye can't naturally see How has this product impacted society in a positive way? What are some innovations that this product has undergone since its original invention? Which of these areas of technology best classifies the artifact? I would change the amount of curvature in the lens to increase the amount of magnification of the magnifying glass Roger Bacon, an english philosopher, scientist and Franciscan Friar is created with the invention of what we commonly refer to today as a magnifying glass. Who was the original inventor and when was this product invented? What is the purpose of your artifact? How has this product impacted society in a negative way? The magnifying glass is made to allow people to see small things enlarged. Strong magnifying glasses can help you see things invisible to the naked eye. Some innovations would be that the magnifying glass was made more portable. For example, there is a hand held video magnifier that can help you read, view maps, menus, phone books, and medication labels. Most magnifying glasses are double convex lenses used to make objects appear larger away from the lens the image will flip appearing 15 twice the focal length ( the distance from the optical center of a lens to the pant where the light rays coverage ) of the lens.

Transcript: MAGNIFYING GLASSES By: Shannon Dietsch 5/31/2022 Function MAGNIFYING GLASS HOW IT FUNCTIONS A magnifying glass is a convex lens made of either glass or plastic. when light hits the glass at a certain point it bends towards the center of the lens. Leaving the glass makes it refract even more, meaning, at some point, these rays of light merge with each other. RAY DIAGRAM Ray diagram WHY IS IT USED? Magnifying glasses are optical devices used for viewing details of objects with some magnification. Magnifying glasses are also sometimes used to help people with vision problems. And magnifying glasses can be put on stands to make microscopes, which scientists like chemists and biologists use to do research. WHY IS IT USED HOW ITS USED A magnifying glass is used by holding it too the object you would like to see magnified and look through the glass part of it, then you should see the object but magnified. HOW IS IT USED EFFECTIVENESS HOW EFFECTIVE ARE THEY Magnifying glasses are really effective for some professions like geologists when identifying things like rocks and fossils and crystals and like a jeweler that uses a magnifying glass too make ring or some earrings. and surgeons use special types of magnifying glasses to preform surgery's so in conclusion the magnifying glass is extremely useful to many people CITATIONS CITATIONS Huntington, M.
