The magnetic field component of an EM wave propagating through a nonmagnetic medium (po) is = Determine: H=25 sin (2 x 10't + 6x) a, mA/m (a) The direction of wave propagation. (b) The permittivity of the medium. (c) The electric field intensity.

A uniform plane wave has a wavelength of 2 cm in free space and 1 cm in a perfect dielectric. What is tbe relative permittivity of the of the dielectric ?

An wave is travelling through a dielectric medium whose relative permittivity is 2.8 and relative permeability is 1.8. What will be the speed of the wave?

Problem 6. In what situations are the group and phase velocities equal for an electromagnetic wave?

One graph shows a particle's movement on a string as a function of time. Its amplitude is 2m, the period is 0.5s, and frequency, 2Hz. The second graph shows the same wave but as a function of distance. What would be its amplitude, wavelength, and wave speed? (my answers were amplitude: 2, the wavelength of 0.4, and wave speed of 1. but one of them seem to be incorrect).

Microwave

An electromagnetic wave of the form E = 2 Sin(kx – wt)î B Cos(kx – wt)j travels though a media with & = 2 l =1 at 9Hz. What is the waves velocity?

Radio waves normally have their E and B fields in specific directions, whereas visible light usually has its E and B fields in random and rapidly changing directions that are perpendicular to each other and to the propagation direction. Can you explain why?

According to the book the answer is 29.8

(t) = Fejtáx with is The wave parameters M2 = 4.5 μ01 E2 = 1.280. Calculate the magnetic field phasor and time-Overased pgniting vector for this wave. with electric field phasor propapating in a perfect dielectric medium 4) you are given a plane wave

The magnetic field amplitude associated with a transverse EM wave is 50 mA/m. What will be amplitude of the electric field?

I have tried answering this problem and I've arrived at an answer of 1.287 or 1.29, but this answer is marked wrong. To anyone who is good at electromagnetics please help me and show me how this problem is done. Thank you.
