Questions and Answers

Which phenomenon is most commonly observed to experience refraction?

All waves

Water waves

Light waves (correct)

Sound waves

What determines how much a wave is refracted?

Change in wave speed

Initial direction of wave propagation

Both change in wave speed and initial direction of wave propagation (correct)

None of the above

What does Snell's law state?

The ratio of the sines of the angle of incidence and angle of refraction is equal to the ratio of phase velocities in the two media

The ratio of the sines of the angle of incidence and angle of refraction is equal to the ratio of refractive indices of the two media (correct)
