Find the frequency of the wave if the wavelength is 5 cm and the wave speed is 150 km / s.

Given:
L = 5 centimeters = 0.05 meters – wavelength;
c = 150 kilometers per second = 150 * 10 ^ 3 meters per second – wave propagation speed.
It is required to determine the frequency of the wave v (Hertz).
To find the frequency of the wave, you need to use the relationship:
L = c / v, hence:
v = c / L = 150 * 10 ^ 3 / 0.05 = 3000 * 10 ^ 3 Hertz = 3 MHz (high frequency range).
Answer: the wave frequency is 3 MHz.
