JEE MAIN - Physics (2024 - 31st January Evening Shift - No. 1)
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:
Statement I is incorrect but Statement II is correct.
Both Statement I and Statement II are correct.
Statement I is correct but Statement II is incorrect.

Explanation
$$\begin{aligned}
& \frac{1}{2} \varepsilon_0 \mathrm{E}^2=\frac{\mathrm{B}^2}{2 \mu_0} \\
& \because \mathrm{E}=\mathrm{CB} \text { and } \mathrm{C}=\frac{1}{\mu_0 \varepsilon_0}
\end{aligned}$$
