Radiation pressure on any surface is :

Radiation pressure on any surface (for given intensity):

Radiation pressure on any surface (for given intensity):

Sunlight falling vertically on a surface at the sea level has an intensity of 1600Wm^(-2) .Assuming 100% of the incident light is absorbed,the radiation pressure on the surface is

Radiation emitted by a surface is directly proportional to

Radiation emitted by a surface is direclty proportional to
