Question

Radiation pressure on any surface:
A. is dependent on the wavelength of the light used.
B. is dependent on the nature of surface and intensity of light used.
C. is dependent on frequency and nature of surface.
D. depends on the nature of the source from which light is coming and on the nature of the surface on which it is falling.

Answer 1

Hint: Every light device will emit the heat and radiation, as we know that the meaning of heat and the radiation is the emission of energy in terms of waves from one medium to another medium only in space. The pressure is the force that we named for the pull or push applied on any liquid particles or the gaseous particles. If we push or pull any solid particle, then it is called the force.

Complete step by step answer:
There will be a number of surfaces that will reflect the light, absorb the light and even there are few materials that will absorb and at the same time, reflect some portion of the light.
As the radiation pressure consists of coefficient of type of surface (whether it is reflecting or absorbing).
If the material is purely absorbing the light without any reflection, then we can say that the coefficient of radiation is 1. If the material is purely reflecting, then the coefficient of radiation can be taken as 0.
By this statement, we can say that the light radiation pressure is a dependent type of surface and independent of the type of light or wavelength of the light.
Therefore, radiation pressure on any surface is dependent on the nature of the surface and intensity of light; it means option (B) is correct.

Note:In this solution, we may confuse the term radiation because it is a rare term that we use, radiation is not similar to the other terms. We should be very clear about the types of materials that reflect the light rays and absorb the light rays and we should be aware of their terminology too.
