Hiya!
I have some general questions about EM waves since i am somewhat lost from reading and may have misuderstood what I read.
1) does all EM waves travel through a vacuum? if so are they the same speeds/proportional/inporportional to their frequency.
2) I now that EM waves are transverse, correct? but can they travel through pretty much anything?
3) Let's say in a vacuum, the velocity of all EM waves are they nearly 3.00 x 10^8 m/s or what?
Now for my homework question? An EM wave traveling to the east. AT one instant at a given point its E vector points straight up. what is the direction of its vector?
my answer is south unless my right hand rule i am using is actually my left hand facing in some weird direction. can you help me please or am i correct?
Thanks!
