If a parallel beam of light having intensity I is incident normally on a perfectly reflecting surface, the force exerted on the surface, equal F. When the surface is held at an angle theta , the force is

A radiation of frequency v_0 falls at an incident angle of 30^@ on a perfectly reflecting surface. Calculate the change in the momentum .

Light with an enargy flux of 25xx10^(4) Wm^(-2) falls on a perfectly reflecting surface at normal incidence. If the surface area is 15 cm^(2) , the average force exerted on the surface is
