Question

Which of the following correctly defines wave speed?


The distance a wave travels per unit of time


The number of waves that pass a point in one second


The height of the wave from its rest position


The distance between two consecutive crests

Answer 1

"The distance a wave travels per unit of time" is correct.

Briefly:
- Wave speed (v) = distance/time, and v = frequency (f) × wavelength (λ).
- The other choices are frequency (number of waves per second), amplitude (height from rest), and wavelength (distance between crests).
