Given below are two statements : Statement I : Electromagnetic...

Given below are two statements :

Statement I : Electromagnetic waves are not deflected by electric and magnetic field.

Statement II : The amplitude of electric field and the magnetic field in electromagnetic waves are related to each other as E0=μ0ε0B0{E}_{0} = \sqrt{\dfrac{{\mu}_{0}}{{ε}_{0}}}{B}_{0}.

In the light of the above statements, choose the correct answer from the options given below:

Options

  1. AStatement I is true but statement II is false
  2. BBoth Statement I and Statement II are true
  3. CStatement I is false but statement II is true
  4. DBoth Statement I and Statement II are false

Correct answer

A. Statement I is true but statement II is false

Step-by-step solution

Statement-I is correct as Electromagnetic waves are neutral.

Statement-II is wrong as

c=E0B0⇒1μ0ε0=E0B0⇒E0=1μ0ε0B0c = \dfrac{{E}_{0}}{{B}_{0}} ⇒ \dfrac{1}{\sqrt{{\mu}_{0}{ε}_{0}}} = \dfrac{{E}_{0}}{{B}_{0}} ⇒ {E}_{0} = \sqrt{\dfrac{1}{{\mu}_{0}{ε}_{0}}}{B}_{0}
