Light, Mirrors, and Lenses

Front

What is white light made of?

Back

White light is a combination of light waves of many different wavelengths.

Front

What is a translucent material?

Back

A translucent material allows some light to pass through but not enough to see clearly through it.

Front

Which medium has the highest index of refraction?

Back

Glass has the highest index of refraction compared to vacuum, air, and water.

Front

What is a concave lens?

Back

A concave lens is a lens that is thinner in the center than at the edges and causes light rays to diverge.

Front

What happens to light when it passes through a concave lens?

Back

Light passing through a concave lens will diverge (spread apart).

Front

What is the definition of refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What is the index of refraction?

Back

The index of refraction is a measure of how much light slows down in a medium compared to its speed in a vacuum.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light when it hits a surface, while refraction is the bending of light as it passes through different media.

Front

What is a convex lens?

Back

A convex lens is thicker in the center than at the edges and causes light rays to converge.

Front

What happens to light when it passes through a convex lens?

Back

Light passing through a convex lens will converge (come together).
