Aradio station broadcasts at a frequency of 1.5 × 108 hz. the speed of an electromagnetic wave is a constant, 3.0 × 108 m/s. what is the wavelength of the radio wave?

The relationship between frequency and wavelength for a wave is given by:

where 
is the wavelength
c is the speed of light
f is the frequency

Using the data of the problem, we can find the wavelength of the radio wave:

Answer: fn = wcos50 = 38.89(9.81)(cos50) = 245.23 n
