Consider the following statements regarding electromagnetic waves: Statement-I: Electromagnetic waves are transverse waves in which the electric field and magnetic field oscillate perpendicular to each other and to the direction of propagation. Statement-II: The speed of electromagnetic waves in vacuum depends only on the permittivity and permeability of free space. Statement-III: In electromagnetic waves, the ratio

Options

  1. AAll four statements are true.
  2. BStatement-I, Statement-II, and Statement-III are true; Statement-IV is false.
  3. CStatement-I and Statement-III are true; Statement-II and Statement-IV are false.
  4. DStatement-II and Statement-IV are true; Statement-I and Statement-III are false.

Correct answer

B. Statement-I, Statement-II, and Statement-III are true; Statement-IV is false.

Step-by-step solution

- Statement-I: This is true. Electromagnetic waves are transverse in nature, with the electric field ( ( E )) and magnetic field (B) oscillating perpendicularly to each other and the direction of wave propagation. - Statement-II: This is true. The speed of electromagnetic waves in a vacuum is given by: (c= 1 ₀ ₀ )
