I'm a little unsure of my own answers to these questions. Hopefully I'll clear up my misconceptions.
1. If I measure the E-field and B-field at a point in space where there is an EM wave, would I be able to determine the direction it propagates from?
My Ans: I don't think so, since when you do a reading a a point, you only get the scalar value
2. If a point charge +q lies on the x-axis and is in the path of a sinousoidal EM wave, will the point charge move?
My Ans: I believe it would just oscillate at that point
3. Most vehicles have got upright and vertical receiving antennas. What does this tell about the E-field polarization of the radio waves that are being broadcasted?
My Ans: It is vertical.
4. Does electromagnetic standing waves have energy? Does it have momentum?
My Ans: Yes. Yes
Could anyone go through my answers and let me know if I have any misconceptions?
Thanks!
