MCQ

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:

A
Statement $I$ is incorrect but Statement $II$ is correct
✓
Both Statement $I$ and Statement $II$ are correct.
C
Both Statement $I$ and Statement $II$ are incorrect.
D
Statement $I$ is correct but Statement $II$ is incorrect.

✓

Answer

Correct option: B.

Both Statement $I$ and Statement $II$ are correct.

b
$\frac{1}{2} \varepsilon_0 \mathrm{E}^2=\frac{\mathrm{B}^2}{2 \mu_0}$

$\because \mathrm{E}=\mathrm{CB} \text { and } \mathrm{C}=\frac{1}{\mu_0 \varepsilon_0}$
