Back

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

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.

Back

A magnifying glass works by refracting light to enlarge the appearance of an object.

Front

What happens to light when it passes through a prism?

Back

Light is refracted and dispersed into its component colors.

Front

What is total internal reflection?

Back

Total internal reflection occurs when light hits a boundary at an angle greater than the critical angle, causing it to reflect entirely back into the medium.
