Question

when an Electromagnetic wave fall on a surface it exerts pressure on the surface this process is called dash pressure​

Answer 1

Answer:Radiation pressure

Explanation:Radiation pressure is the pressure exerted upon any surface due to the exchange of momentum between the object and electromagnetic field

Answer 2

Electromagnetic wave fall on a surface it exerts pressure on the surface this process is called Radiation pressure​

Explanation:

• Whenever a surface is subjected to electromagnetic wave exchange of momentum takes place between the incident surface and the electromagnetic waves.  
• By the law of Friction, this exerts pressure, and as it is created by the radiation it is termed as radiation pressure.  
• Johannes Kepler was the first one to put forward this idea.
• Newton's Third law of motion and Law of conservation of momentum can be used to understand this concept.
