Homework Statement
The sun emits 3x1032J of energy every day. Assume it emits only yellow light (6x10-7m wavelength. a. What is the energy of each photon of yellow light? b. How many photons does the sun emit every day?
Homework Equations
E = hf
The Attempt at a Solution
So I think I have question A complete, my solution is the following.
F = (3x108 m/s)/(6x10-7 m) = 5x1014 Hz
H = (6.6x10-34Js)
E=h*f (6.6x10-34Js)(5x1014Hz) = 3.3x10-19 J
Or E = 2 eV
But problem B I am stumped. I don't even know where to begin to figure this out. Can anyone help put me in the right direction?
