Question
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=μ0ε0−−√B0.In the light of the above statements, choose the correct answer from the options given below:Statement I is true but statement II is falseBoth Statement I and Statement II are trueStatement I is false but statement II is trueBoth Statement I and Statement II are false
Solution
Statement I is true but statement II is false.
Explanation:
Statement I: Electromagnetic waves are not deflected by electric and magnetic fields. This is true because electromagnetic waves are composed of oscillating electric and magnetic fields that are perpendicular to each other and to the direction of propagation. Therefore, they do not interact with external electric or magnetic fields and are not deflected by them.
Statement II: The amplitude of the electric field and the magnetic field in electromagnetic waves are related to each other as E0=μ0ε0−−√B0. This is false. The correct relationship between the amplitudes of the electric field (E0) and the magnetic field (B0) in an electromagnetic wave in free space is given by E0 = cB0, where c is the speed of light in vacuum. The given equation incorrectly relates the amplitudes of the electric and magnetic fields to the permeability of free space (μ0) and the permittivity of free space (ε0).
