Concave and Convex Lenses Review

Front

What is a concave lens?

Back

A concave lens is a lens that is curved inward on both sides, causing light rays to spread apart as they exit the lens.

Front

What is a convex lens?

Back

A convex lens is a lens that is curved outward on at least one side, causing light rays to converge to a point.

Front

What is the difference between concave and convex lenses in terms of shape?

Back

A concave lens is curved inward, while a convex lens is curved outward.

Front

What type of image does a concave lens produce?

Back

A concave lens produces virtual images that are upright and smaller than the object.

Front

What type of image does a convex lens produce?

Back

A convex lens can produce real images that are inverted and larger than the object, depending on the object's distance from the lens.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.
