Question
What is the velocity called that describes how a constant phase of a wave is propagated, given by the relation v = ω/k?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Page 3 explicitly states: 'v is called the phase velocity because that is the velocity with which a constant phase is propagated: kx - ωt = const.'
Hint
Consider the speed at which a specific point on the wave (like a crest or trough) travels.
