031x10^8 s-1) = 2.The trick here is that 1 Hz = 1 sec^-1 and 1 mHz = 10^6 Hz.......
how do u do thiss?

calculate wavelengh of an FM radio station with a frequency of 103.1 mHz

-
frequency and wavelength are two wave properties, which are related by the following equation:

c = λv

where c is the speed of light, λ is the wavelength, and v is the frequency of the wave. To solve your problem all you have to do is rearrange the equation and plug the corresponding values with the right units:

λ = c/v = (2.998x10^8 m/s)/(1.031x10^8 s-1) = 2.908 m

The trick here is that 1 Hz = 1 sec^-1 and 1 mHz = 10^6 Hz.
