Question

A 15,000-watt radio station transmits at 1700 kHz.


Calculate the energy of a single photon at the transmitted frequency.

A). 1.1 x 10^ -27 J/photon

B). 9.9 x 10^ -30 J/photon

C). 1.1 x 10^ -30 J/photon

Answer 1

$E_{\gamma}=hf= (6.62\times10^-^3^4 Js)(1700\times10^3Hz)=1.12\times10^-^2^7J/photon$
Answer A
