A radio station's channel, such as 100.7FM or 92.3 FM, is actually it's frequency in megahertz, where 1 MHz = 10^6 Hz and 1 Hz = 1s-1. Calculate the broadcast wave length of the radio station 96.90 FM.
You have to use the equation c=λν c= the speed of light (3.00x10^8 m/s) λ= the wavelength in m (in this case the unknown) ν= the frequency in Hz or s^-1 (in this case 96.9x10^6 Hz) The frequency of the 96.90 FM radio station is 96.90 MHz which equals 96.9x10^6 Hz and we know the speed of light since it is a constant. with this information we can rewrite the equation as λ=c/ν to get wavelength. λ=(3.00x10^8 m/s)/(96.9x10^6 Hz) λ=3.10 m
