    What is the direction and explanation of electromagnetic radiation?

    Sorry for not responding sooner - been extremely busy with school lately. One final question, I think I feel better about the rest of this so far. If, in the example gif I posted earlier, the charge is accelerating parallel to the z axis, why isn't there a radiative field in the z-direction? It...

    What is the direction and explanation of electromagnetic radiation?

    I guess the explanation behind EM radiation is pretty straightforward. I may have overcomplicated it in my head earlier. But I'm still not 100% confident on the directions of the fields/their propagation. For example, how dow we know that in this situation, they propagate in the positive y...

    What is the direction and explanation of electromagnetic radiation?

    This isn't really a homework question, but I felt it was better suited here than in General Physics. I'm looking for more of a general explanation than anything. I was able to do my homework for this section on my own (mostly), but I feel like I still really have no idea what is actually going...

    How Much Energy is Needed to Move a Satellite to Infinity from Earth Orbit?

    Ah, okay, that makes sense now. Thanks for your help, and the warm welcome! To start a new thread I just went to the specific forum (Introductory Physics in this case) and clicked "New Topic" at the top right. It's in the same location as "New Reply" on this page.

    How Much Energy is Needed to Move a Satellite to Infinity from Earth Orbit?

    A satellite of mass 7500 kg orbits the Earth in a circular orbit of radius of 7.3(10^6) m (this is above the Earth's atmosphere). The mass of the Earth is 6.0(10^24) kg. What is the minimum amount of energy required to move the satellite from this orbit to a location very far away from the...
