Radiations of wavelength 200 nm propagating in the form of a parallel beam, fall normally on a plane metallic surface. The intensity of the beam is 5mW and its cross sectional area 1.0mm^(2) . Find the pressure exerted by the radiation on the metallic surface, if the radiation is completely reflected.

A beam of light having wavelength 5000 Å is incident on a plane metallic surface. The intensity of the incident beam of light is 40 watt and its cross-sectional area is 2mm^(2) . What will be pressure (in "dyne"//cm^(2) ) exerted by radiation on the metallic surface if 50% of it is reflected back by metallic surface.

If the intensity of the incident radio wave of 1 "watt"//m^2 is reflected by the surface, find the pressure exerted on the surface.
