The intensity of sunlight at the earths surface

Reference no: EM13663034

The intensity of sunlight at the earth's surface is 1400W/m², and the average wavelength is 550 nm.

1) How many photons per second are absorbed with a perfect blackbody surface of area 1.25m² perpendiculars to the sun's rays?

2) How much momentum is transferred to the plate in a 5-hour interval?
