Answer:
wave speed
Explanation:
A wave is a disturbance that transmits energy from one place to another without the actual displacement of the particles of the medium.
To find the wave speed we need to determine the product of its frequency and wavelength.
Wave speed = Frequency x wavelength
Frequency of wave is the number of wave that passes through a point at a unit time.
Wavelength is the displacement of a complete wave train.
