Question

Assume that a certain location on the Earth reflects 28.0% of the incident sunlight from its clouds and surface. (a) Given that the intensity of solar radiation at the top of the atmosphere is 1368 W/m2, find the radiation pressure on the Earth, in pascals, at the location where the Sun is straight overhead.

Answer 1

Answer:

Explanation:

radiation pressure = I / c , I is intensity of radiation , c is velocity of light.

intensity falling on the earth = 1368 x 72 / 100

I = 984.96 W / m²

Radiation pressure =  I / c

= 984.96  / 3 x 10⁸

= 328.32 x 10⁻⁸ pascal .
