Snell's Law Practice

What is Snell's Law?

• It describes the relationship between the angles of incidence and refraction when light passes through different media.

• It explains the reflection of light from a mirror.

• It defines the speed of light in a vacuum.

• It describes the dispersion of light through a prism.
