Q 12-08-069JEE MainJEE Main 2024 (31 Jan, Shift 2)Easy
Given below are two statements:
Statement I: Electromagnetic waves carry energy as they travel through space and this energy is equally shared by the electric and magnetic fields.
Statement II: When electromagnetic waves strike a surface, a pressure is exerted on the surface.
In the light of the above statements, choose the most appropriate answer from the options given below:
Answer: (B) Both Statement I and Statement II are correct
Statement I is correct: the average energy densities $\tfrac12\varepsilon_0E^2$ and $\dfrac{B^2}{2\mu_0}$ are equal.
Statement II is correct: EM waves carry momentum, so they exert radiation pressure on a surface they strike.
