In the context of transverse waves, what term describes the speed at which a wave travels through a medium?
A
Wave speed (wave velocity)
B
Wave period
C
Wave amplitude
D
Wave frequency
Verified step by step guidance1
Understand that a transverse wave is a wave where the oscillations are perpendicular to the direction of wave propagation.
Recall that the speed at which any wave travels through a medium is called the wave speed or wave velocity.
Recognize that wave speed is different from wave period (the time for one complete oscillation), wave amplitude (the maximum displacement), and wave frequency (the number of oscillations per second).
Use the fundamental relationship between wave speed \(v\), frequency \(f\), and wavelength \(\lambda\): \(v = f \times \lambda\).
Conclude that the term describing the speed at which a wave travels through a medium is the wave speed (or wave velocity).
