Details on electromagnetic waves?

[elabed haidar]

i really want to understand the lesson so bad i read the lesson 10 times and the lesson is like 50 pages and i still don't get the concept of how electromagnetic waves were originated??
and what about polarization? please with all the details you have and thank you

You're going to have to post some specific questions on what you don't understand. An overview of EM waves is available in many different parts of the internet and a simple google search will show you many.

you are right let me be more accurate :
1) we know that the electromagnetic waves is made of electric field and magnetic fields i just want to know how each of them is dependent of the other?
2) what about polarization ? i know it is when the beam of light is going toward one direstion but what i don't understand how is it related to the electic field
3) reflection by polarization? why is it when we reach brewster angle we get polarization ?
please the more deeper you get the better i don't want to know the concept like our professor does i want to know especially i am doing physics and thank you very much

Drakkith is right, you should try to look up electromagnetism in books for physics students. Does your professor recommend any?
Maybe try:
Electricity and Magnetism - W.J. Duffin
Electromagnetism - IS Grant and WR Phillips
just google some.

In response to the questions
1) The Maxwell equations show explicitly how they depend on each other.
2) A general beam of light going in one direction has components of the electric field going in all directions perpendicular to its motion (is unpolarised). But a polarised beam has its electric field components confined to a particular direction.
3) At the surface between two materials, there are several conditions on the electric and magnetic fields. It is these conditions that cause polarisation of an incident electromagnetic wave at certain angles.

Sorry I haven't answered any of the questions in depth, but they are very broad, try a book on electromagnetism.

thank you but here is the thing , i don't like to judge or criticize anyone but unfortunately our professor doesn't know how to teach , he thinks that studying telecommunication engineering makes him a great professor in P103 , which we are taking right now . I am sorry in conclusion he doesn't know how to teach
thank you Mr bruceW and your right i have to study on my own but i am trying to find the website which will help me understand electromagnetic waves ina an easy but detailed way

Hyperphysics is a good website, gets the main points across http://hyperphysics.phy-astr.gsu.edu/hbase/emcon.html#emcon
A good book with worked examples would give a better understanding

This part of the website might be more useful to answer your questions http://hyperphysics.phy-astr.gsu.edu/hbase/ligcon.html#c1
