Answer:
Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency.

Speed = Wavelength x Frequency.
v the velocity of the wave
f frequency of the wave
\lambda. wavelength.
Solved Example
: A sound wave has a wavelength of 1.5 mm, then find out its frequency.
Solution:
Given:
Wavelength, \lambda = 1.5 mm,
Speed of sound, v = 343.2 m/s.
The frequency is:
f = \frac{v}{\lambda }\\
f = \frac{343.2}{ 1.5 × 10^-^2}
= 22.8 KHz.
The frequency of the sound waves is 22.8 kHz.
