Electromagnetic...

In electromagnetic wave, according to Maxwell, changing electric field gives.

The capacity of a parallel plate air capacitor is $$2 \mu F$$ and voltage between the plates is changing at the rate of $$3 {V}/{S}$$. The displacement current in the capacitor is:

Unpolarized light falls first on polarizer $$\left( P \right) $$ and then on analyzer $$\left( A \right) $$. If the intensity of the transmitted light from the analyser is $$\dfrac { 1 }{ 8 }$$th of the incident unpolarized light. What will be the angle between optic axes of $$P$$ and $$A$$?

Light is an electromagnetic wave. Its speed in vacuum is given by the expression

The Electromagnetic wave travelling in a medium has relative permeability $$1.3$$ and relative premittivity $$2.14$$. The speed of EM wave in that medium will be.

In an electromagnetic wave, the electric magnetising fields are $$100V/m$$ and $$0.265 A/m$$. The maximum energy flow is?

Electromagnetic waves travel only through.

The time varying electric and magentic fields are $${E}=E_x\hat{i}+E_x\hat{j}+E_z\hat{k}$$ and $$B=B_x\hat{i}+B_y\hat{j}+B_z\hat{k}$$ respectively. They generate a plane electromagnetic wave travelling towards x-direction in pair of space.

If the magnetic field of an electromagnetic wave is given as $$B_y=2\times 10^{-7}\sin(10^3x+1.5\times 10^{12}t)$$ tesla, the wavelength of the electromagnetic wave is

If a source is transmitting electro-magnetic waves of frequency $$8.196\times 10^{6}Hz$$, then the wavelength of the electro-magnetic waves transmitted from the source will be
