Homework Statement
An area of 2 sq. meter is lit with power 10W/m^2 with light on wave length equal to 600nm.
What is the photon flux that HIT the 2 sq. meter surface.
Homework Equations
E=hv - plank const and frequency (c/lambda)
Photon flux of EMITTED source is flux=N/t=P/hv
The Attempt at a Solution
It seems, that somehow the emitted flux P/hv has to be connected with flux that hit the surface...
