Problem: In the 25-ft Space Simulator facility at NASA's Jet Propulsion Laboratory, a bank of overhead arc lamps can produce light of intensity 2500W/m2 at the floor of the facility. (This simulates the intensity of sunlight near the planet Venus.)A) Find the average radiation pressure (in pascals) on a totally reflecting section of the floor.B) Find the average radiation pressure (in atmospheres) on a totally reflecting section of the floor.

For an object where the waves are totally reflected, the radiation pressure is given by:

Prad=2Ic 

A)

From the boxed equation:

Prad=(2)(2500)3.0×108
