What is the energy of a microwave photon of frequency 2.5x 10^9 hz?
answer in units of j.

the energy of a microwave photon E = 16.565 x 10^-25 Joule

Explanation:

To get the energy of the photon we are going to use this formula :                                       E = hf

when E is the energy of the photon which we need to calculate

h is Planck's constant = 6.626 x 10^-34 J.S

f is the photon of frequency = 2.5 X 10^9 Hz

so by substitution:

the energy of a microwave photon E = 6.626 x 10^-34 J.S * 2.5 X 10^9 S-1

  = 16.565 x 10^-25 Joule
