5. The energy of a photon is quantized. That is, each photon a wave carries contains the sa wave the EM wave specific amount of energy. The energy of a photon is dependent on the frequency of and can be found using the following equation: Ephoton-hv h-Planck's constant: 6.63x10 Js 1 Joule = 1 kgmWS2 (the Joule is a unit of energy) A radio station has a frequency of 3.8 x 1010 Hz. What is the energy in joules (J) of one photon of this radiation. Hint. Recall v- Known variables and constants: Unknown variables: Applicable equations Substitute and solve: Final answer

Explanation / Answer

answer 5: E=hv where v= frequency= 3.8*108 hz

=6.63*10-34*3.8*108

=25.2*10-24

answer 6: E= hc/wavelenght where c= velocity of light

= 6.63* 10-34* 3*1010    /242*10-9m

=0.082*10-15J
