A radio wave has a wavelength of 150m. If the velocity of radio waves is free spaces is 3 x 10\(^8\) ms\(^{-1}\), calculate the frequency of the radio wave
Question 1 Report
A radio wave has a wavelength of 150m. If the velocity of radio waves is free spaces is 3 x 10\(^8\) ms\(^{-1}\), calculate the frequency of the radio wave
Answer Details
The velocity of a wave is given by the product of its frequency and wavelength, i.e.,
velocity = frequency x wavelength
Rearranging this equation, we get:
frequency = velocity / wavelength
Substituting the given values, we get:
frequency = (3 x 10^8 m/s) / (150 m)
frequency = 2 x 10^6 Hz
Therefore, the frequency of the radio wave is 2.0 x 10^6 Hz.
