Question

What is meant by the speed of the wave?

Options

• The speed with which a common tangent moves towards the source

• The speed with which the wavefront moves outwards from the source

• The speed with which the amplitude becomes zero in the forward direction

• The speed with which all points move parallel to the wavefront

Answer 1

The speed of the wave is the speed with which its wavefront moves outwards from the source. It describes the outward propagation of the disturbance.
