Question

A radio station transmits electromagnetic waves of frequency 40MHz. If the speed of these waves is 3 into 10 raised to the power 8 metres per second, what is the wavelength of these waves ?

Answer 1

`lambda approx 0.13m`

Explanation:

`c=flambda`

`lambda = f/c`

`lambda = (40*10^6)/(3*10^8)`

`lambda = 13.33 *10^-2`

`lambda approx 0.13m`
