Calculate the broadcast wavelength of the radio station 99.90 fm. seconds

The radio waves are electromagnetic wave, so it travels with velocity of light i.e .

We can use the relation between frequency, wavelength and speed as

Here c is speed of light, is wavelength and f is frequency and its value is given 99.90 FM, it is actually in megahertz  (i.e 99.90 MHz).

Therefore,

.

Thus, the broadcast wavelength of the given radio station is 3.003 m.
