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.
