A certain radio station broadcasts on a frequency of `980 kHz` (kilohertz). What is the wavelength of electromagnetic radiation broadcasts by the radio station ?

Answer

306 m

Explanation

Frequency, `v = 980 kHz = 980 xx 10^(3) s^(-1)`
Wavelength `lambda = c/v`
`:. " "lambda = (3.0 xx 10^8 ms^(-1))/(980 xx 10^3 s^(-1)) = 306 m`.
