The frequency of AM radio channels is typically on the order

The frequency of AM radio channels is typically on the order of 105 Hz or 106 Hz. What is the wavelength of these waves? FM waves have wavelengths between 1.0 m and 10 m. What is the frequency of these waves?

Solution

wave length = C/V ( V is frequency)

=> A)

wave length = 3*10^8)/(10^5,10^6) = 3*10^2 to 3*10^3 m

B)

wave length = 3*10^8)/(1,10) = 3*10^7 to 3*10^8 m
