Question

If a radio station broadcasts at 92.1 MHz, what is the wavelength of the electromagnetic radiation?

Answer 1

`3.26"m"`

Explanation:

`f*lambda=c`

`f` is frequency
`lambda` is wavelength
`c` is speed of EM radiation in vacuum

`(92.1xx10^6"Hz")*lambda=3.00xx10^8"m/s"`

`lambda=3.26"m"`
