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 $E_{0} = \sqrt{\frac{μ_{0}}{ε_{0}}} B_{0}$ .

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

Options:

Answer:

Solution:

Statement-I is correct as Electromagnetic waves are neutral.

Statement-II is wrong as

$c = \frac{E_{0}}{B_{0}} \Rightarrow \frac{1}{\sqrt{μ_{0} ε_{0}}} = \frac{E_{0}}{B_{0}} \Rightarrow E_{0} = \sqrt{\frac{1}{μ_{0} ε_{0}}} B_{0}$
