Light with an energy flux of Wm falls on a perfectly reflecting surface at normal incidence. If the surface area is cm the average force exerted on the surface is
N
N
To solve this problem, we need to calculate the force exerted by light on a perfectly reflecting surface.The force exerted by light on a surface is given by the change in momentum per unit time. For a perfectly reflecting surface,the change in momentum is twice the momentum of the incident light.The momentum of light is related to its energy flux by the equation:
