Embibe Experts Solutions for Chapter: Electromagnetic Waves, Exercise 2: Exercise-2

Out of the following statement which is not true?

If a light wave passes through a transparent medium (like as glass). Then :

Which of these statement is false :

The $\overrightarrow{E}$ and $\overrightarrow{B}$ vectors associated with an electromagnetic wave are:

An electromagnetic radiation of frequency $v,$ wavelength ${\lambda }_1,$ travelling with velocity $c$ in air, enters a glass slab of refractive index $\mu .$ The frequency, wavelength and velocity of light in the glass slab will be respectively

Assertion : Displacement current arises on account of change in electric flux.

Reason : $i_d={ϵ}_0\left(\frac{d{\Phi }_E}{dt}\right)$

Assertion: Electromagnetic waves are transverse in nature.

Reason: The electric and magnetic fields of electromagnetic waves are perpendicular to each other and also perpendicular to the direction of wave propagation.

Assertion : In an e.m. wave magnitude of magnetic field vector $\overrightarrow{B}$ is much smaller than the magnitude of vector $\overrightarrow{E}.$

Reason : This is because in an e.m. wave $\frac{E}{B}=c=3\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}.$
