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

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

A monochromatic beam of light (lamda=4900A) incident normally upon a surface produces a pressure of 5xx10^(-7)Nm^(-2) on it. Assume that 25% of the light incident in reflected and the rest absorbed. Find the number of photons falling per second on a unit area of thin surface

Electromagnetic radiation with energy flux 50W cm^(-2) is incident on a totally absorbing surface normally for 1 hour : If the surface has an area of 0.05m^(2) , then the avergae force due to the radiaton pressure, on it is,

A beam of white light is incident normally on a plane surface absorbing 70% of the light and reflecting the rest. If the incident beam of light is power P, find the force exerted by it on the surface.

A black totally absorbing piece of carboard of area A=2.0 cm^(2) intercepts light with an intensity of 10 W//m^(2) from a camera strobe light . What radiation pressure is produced on the cardboard by the light ?

Light with an energy flux of 18W//cm^(2) falls on a non-reflecting surface at normal incidence. The pressure exerted on the surface is

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.
