Find the energy, in joules per photon,

Question

radio waves with a frequency of 2.50 * 10^6 1/s.?

 

Answer 1

Find the energy using plank law

E=hν

Here h is the flank constant and ν is the frequency.

h=6.626 x 10^-34 J·s

Substitute 2.50 * 10^6 1/s for ν

E=6.626 x 10^-34 *2.50 * 10^6

  =16.565x 10^-28  J
