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 absorbing section of the floor.B) Find the average radiation pressure (in atmospheres) on a totally absorbing section of the floor.

FREE Expert Solution

Radiation pressure on an object absorbing all the light:

Prad=Ic, where I is the intensity of lightwave and c is the speed of light.

A)

From the boxed equation:

Prad=25003.0×108
