The distance traveled by a wave in unit time is termed as:
Correct answer: D. Wave speed
- A. Wavelength
- B. Amplitude
- C. Displacement
- D. Wave speed
Explanation
Wave speed is the distance a wave travels per unit time, equal to frequency times wavelength. Wavelength is the distance between successive crests, amplitude is the maximum displacement, and displacement is a particle's position relative to its mean position.

About Wave Speed
Wave speed is the rate at which a disturbance or wave pattern travels through a medium, given by v = fλ, where f is frequency and λ is wavelength. Questions examine how speed changes between media, the relation among frequency, wavelength and period, and why wave speed is not the same as particle vibration speed.
