Refraction of waves occurs when the waves move through different media (such as air and water), causing the waves to change direction. True or False

Question

anonymous · Answer

It is customary to put Physics questions in the appropriate section but here goes anyway: refraction is observed when light or another wave energy encounters a medium of different refractive index at an oblique angle causing a change in direction. In case you think you're getting a poor answer froma Biologist, you can look it up here: http://en.wikipedia.org/wiki/Refraction
