Reflection and Refraction

Front

What is the speed of light in vacuum?

Front

What is the angle of reflection (θ_r)?

Back

The angle of reflection (θ_r) is equal to the angle of incidence and is measured from the normal. In this case, it is 34^o.

Front

What are the primary colors of light that humans can see?

Back

The primary colors of light that humans can see are Red, Green, and Blue.

Front

What color is produced by mixing Blue and Green light?

Back

Mixing Blue and Green light produces Cyan light.

Front

What color is produced by mixing Red and Blue light?

Back

Mixing Red and Blue light produces Magenta light.

Front

Define reflection in the context of light.

Back

Reflection is the bouncing back of light rays when they hit a surface.

Front

Define refraction in the context of light.

Back

Refraction is the bending of light rays as they pass from one medium to another with a different density.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What happens to light when it passes from air into water?

Back

When light passes from air into water, it slows down and bends towards the normal due to refraction.

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.
