Force Exerted By A Light Beam On A Surface

A parallel beam of monochromatic light of frequency v is incident on a surface. Intensity of the beam is I and area of the surface is A. Find the force exerted by the light beam on the surface for following cases– (i) the surface is perfectly absorbing and the light beam is incident normally on it. (ii) the surface is perfectly reflecting and the light beam is incident normally. (iii) the surface is perfectly absorbing and the light beam is incident at an angle of incidence theta . (iv) the surface is perfectly reflecting and the light beam is incident at an angle of incidence theta .

What is the force exerted by a photon beam of intensity 1.4kW//m^(2) , if it falls on a perfectly absorbing disc of radius 4 metre ?

A square plate of side length L absorbs all radiation incident on it. A point source of light is placed at a point P which is directly above a corner of the plate at a height L. The incident light on the plate produces a force of magnitude F_(0) on the plate. Calculate the magnitude of force on the plate if the source is moved to a point Q (Q is midpoint of the line PR).

In Young's double slit experiment, the fringes are displaced by a distance x when a glass plate of one refractive index 1.5 is introduced in the path of one of the beams. When this plate in replaced by another plate of the same thickness, the shift of fringes is (3/2)x. The refractive index of the second plate is
