Determine the number of photons per second per square meter

Reference no: EM13265889

Light is shining perpendicularly on the surface of the earth with an intensity of 131 W/m2. Assuming all the photons in the light have the same wavelength (in vacuum) of 677 nm, determine the number of photons per second per square meter that reach the earth.
