Front

Define reflection in the context of light.

Back

Reflection is the bouncing back of light when it hits a surface.

Front

Define refraction in the context of light.

Back

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

Front

What is Snell's Law?

Back

Snell's Law relates the angles of incidence and refraction to the indices of refraction of the two media.

Front

State Snell's Law formula.

Back

n1 * sin(θ1) = n2 * sin(θ2)

Front

What does the index of refraction indicate?

Back

The index of refraction indicates how much light slows down in a medium compared to vacuum.
