Convex and Concave Lenses Flashcard

Front

What is a lens?

Back

A transparent glass or plastic with curved sides that can bend light.

Where does the image form when light rays pass through a concave lens?

Behind the lens.

Front

Where does the image form when light rays pass through a convex lens?

Back

At the focal point.

Front

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

Back

They are refracted towards the normal line and converge at a focal point.

Front

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

Back

They are refracted away from the normal line and diverge.

Front

What is a convex lens?

Back

A lens that is thicker in the middle than at the edges, causing light rays to converge.

Front

What is a concave lens?

Back

A lens that is thinner in the middle than at the edges, causing light rays to diverge.

Front

What is the focal point of a lens?

Back

The point where light rays either converge or appear to diverge from after passing through the lens.

Front

How do convex lenses affect light rays?

Back

They bend light rays inward, causing them to converge.

Front

How do concave lenses affect light rays?

Back

They bend light rays outward, causing them to diverge.
