Concave and Convex Lenses Review

Front

What is a concave lens?

Back

A concave lens is a lens that is thinner in the center than at the edges, causing light rays to diverge when they pass through it.

Front

What is a convex lens?

Back

A convex lens is a lens that is thicker in the center than at the edges, causing light rays to converge when they pass through it.

Front

How do concave lenses affect light rays?

Back

Concave lenses spread light rays apart, making them diverge.

Front

How do convex lenses affect light rays?

Back

Convex lenses bring light rays together, making them converge.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in speed.

What is the focal point of a lens?

Back

The focal point is the point where light rays converge or appear to diverge after passing through a lens.

What is the difference between real and virtual images?

Back

Real images can be projected on a screen and are formed by converging light rays, while virtual images cannot be projected and are formed by diverging light rays.

Front

What is an application of concave lenses?

Back

Concave lenses are used in car headlights to spread light outwards.

Front

What is an application of convex lenses?

Back

Convex lenses are used in magnifying glasses to enlarge images.

What happens to light rays when they pass through a concave lens?

Back

Light rays spread out after passing through a concave lens.
