This is how you can distinguish between concave and convex lens by learning the features of light rays refracting inside the lenses. When you follow the structure and traits of a concave and convex lens, you will clearly understand the difference in the formulas. The same formula of focal len...

Magnifying glasses and some binoculars useconvexlenses.Concavelenses are used in movie projectors to spread out the image onto the screen (if you look back through the lens, inside the projector, the image will look tiny). Some optical devices, like telephoto lenses for cameras, use a combinati...

A convex lens is also known as a converging lens this lens is invented by Roger Bacon in 1250. When a parallel ray of light passes in this lens, the refracted ray is intersecting in one place. Usually, the convex lens is used in telescopes and magnifying glass. The concave ...
The convex lens is called the converging lens, while the concave lens is called the diverging lens. The convex lens is called a converging lens because it refracts the rays towards the principal axis, so it collects light rays falling on it. The concave
Images created by convex mirrors are also virtual and upright in relation to the object. Where are F and C located in a convex mirror ray diagram? Drawing the original sphere from where the curved mirror was built, C is the center of curvature and coincides with the center of the sphere....
I'm confused about the difference between convex and concave given your examples. You say that "A good example of a concave object would be a bowl or plate." Yet later, you name another convex item: the contact lens. "Soft contact lenses are shaped into a convex configuration," but a ...
