Easy MCQ +4 / -1 PYQ · JEE Mains 2023

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 ${E_0} = \sqrt {{{{\mu _0}} \over {{\varepsilon _0}}}} {B_0}$.

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

  1. A Both Statement I and Statement II are true
  2. B Statement I is true and Statement II is false Correct answer
  3. C Both Statement I and Statement II are false
  4. D Statement I is false but Statement II is true

Solution

<p>Statement I is correct as photon do not carry any charge, hence cannot feel force from either fields.</p> <p>Statement II is wrong as $E_0=cB_0$</p> <p>${E_0} = {{{B_0}} \over {\sqrt {{\mu _0}{\varepsilon _0}} }}$</p>
