Which of the lines on the graph shows how the pressure exerted by radiation being reflected by a surface varies with the intensity of the radiation?
Light with an intensity of 50.0 W/m2 is directed at a 100% reflective surface. The surface has an area of 2.25 m2. What force is exerted by the light on the surface? Use a value of m/s for the speed of light in a vacuum.
Light of constant intensity is directed at a 100% reflective surface. The light strikes the surface at an angle, as shown in the diagram. If , will the radiation pressure exerted by the light on the surface be greater than, less than, or equal to the radiation pressure when ?
