what is the relation between E and H in uniform plane wave
Answers
We are not going to do the maths for this in any detail but if we substitute the above functions of E and H into Maxwell's equations we can show that they work. E and H are orthogonal, as shown by the unit directional vectors, and also have a sinusoidal variation in amplitude. By convention the polarisation is defined by the direction of the E field. The wavelength is the distance traveled in one cycle of E and H. The existence of plane waves was predicted by John Henry Poynting in 1884. To put it exceptionally crudely, a looping Electric field causes a looping magnetic field which causes a looping Electric field etc. and effectively the Electromagnetic wave propagates like a perpetual game of leapfrog.
The relation between E and H in uniform plane wave is given below.
Explanation:
Basically, the electromagnetic fields are made of both electric as well magnetic fields. And the electric field is denoted as E whereas the magnetic field is denoted by H. It is the magnitude of both of them.
Electric field E is also known as E - field and magnetic field H is also known as M - field.
The uniform plane wave does not have mass but have energy as well as momentum.
