JEE Main 2024 — 31 January, Shift 2 — Question 38

Given below are two statements : one is labelled as Statement I and the other is labelled as Statement II:

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 correct answer from the options given below :

  1. Option A:

    Statement I is incorrect but Statement II is correct

  2. Option B:

    Both Statement I and Statement II are correct.

    Correct
  3. Option C:

    Both Statement I and Statement II are incorrect.

  4. Option D:

    Statement I is correct but Statement II is incorrect.

Answer: B

Step-by-step solution

12ε0E2=B22μ0\frac{1}{2} \varepsilon_{0} \mathrm{E}^{2}=\frac{\mathrm{B}^{2}}{2 \mu_{0}} ∵E=CB\because \mathrm{E}=\mathrm{CB} and C=1μ0ε0\mathrm{C}=\frac{1}{\mu_{0} \varepsilon_{0}}
