An electromagnetic wave is propagating along x-axis. At x = 1 m and t = 10 s, its electric vector |$$\overset{-}{E}|  = 6 V/m$$ then the magnitude of its magnetic vector is:

The frequency of electromagnetic wave which is best suitable to observe particle of radius $$3 \times 10^{-4}$$ cm is of the order of

Maxwell in his famous equations of electromagnetism, introduced the concept of

A charged particle oscillates about its mean equilibrium position with a frequency of $${10}^{9}$$ Hz. The frequency of electromagnetic waves produced by the oscillator is

The ratio of amplitude of a magnetic field to the amplitude of electric field for an electromagnetic wave propagating in vacuum is equal to

An electromagnetic wave propagating along north has its electric field vector upwards. Its magnetic field vector point towards.

The amplitude of the magnetic field of a harmonic electromagnetic wave in vacuum is $${B}_{0}$$ = 510 nT. The amplitude of the electric field part of the wave is

Which of the following doesnt represent Maxwells equation?

The electric field associated with an electromagnetic wave in vacuum is given by $$|\overrightarrow { E } |= 40\ cos (kz -6\times{10}^{8}t )$$, where $$E$$, $$z$$ and $$t$$ are in volt per meter, meter and second respectively. The value of wave vector $$k$$ is:

An electromagnetic waves can be produced, when charge is
