Can anybody tell me the basics of EM waves...like what constitutes EM wave...what is displaced...what are electric and magnetic field components...????

em waves constitutes both magnetic and electric field... howewever in vaccum a combination of mutually perpendicular electric and magnetic fields is refrd 2 s an emwaves.... it components are E=E1SINw(T-X/C) AND B=B1SINW(T-X/C) .whr E and B are sinusoidally varying electri field and magnetic field at the position x at time t. ... hope it hlps!

Justwild, Welcome to Physics Forums! Here there are highly educated scientists, engineers and others with tons of experience in science, technology, engineering, and mathematics (STEM) ready to help anyone who is serious about learning.

Now, when you post a question like "Can anybody tell me the basics of EM waves...like what constitutes EM wave...what is displaced...what are electric and magnetic field components...????" you have not shown that you have studied EM waves at all. Would you like someone here to "spoon feed you" some information? Please try using Google, Wikipedia, your teachers, and textbooks to try learning about EM waves first. Then, when you have doubts or questions, post them here. That is what we do here...help others learn.
