The oscillating magnetic field in a plane Electromagnetic wave is given by
B = (8 x 10^-6) sin (2 x 10¹¹ t + 300 πx) T
(i) Calculate the λ of Electromagnetic wave.
(ii) Find the amplitude of electric field.

The magnetic field amplitude of an Electromagnetic wave is 1.6 x 10^-7 T. If the frequency is 30 MHz. determine electric field, any velocity K and λ.

In which way you can establish an instantaneous displacement current of 1.0 A in the space between the parallel plates of 1μf capacitor?

A plane Electromagnetic wave travels in vacuum along z - direction. What can you say about the directions of electric and magnetic field vectors? If the frequency of the wave is 30 MHz. What is its wavelength?

Use the formula E = h૪ (for energy of a quantum of radiation photon) and obtain the photon energy in units of ev for different parts of the Electromagnetic spectrum. In what ways are the different scales of photon energies that you obtain related to the sources of Electromagnetic radiation?
