I have a quick question here, and essentially, I'm wondering what are the differences between a ferrous magnet (more specifically, iron) and a non-ferrous magnet? How would you distinguish between the two? Thanks in advance; any help would be greatly appreciated.

Well, my high school Physics teacher mentioned that, and from Google, the Doppler effect equations for a stationary source, moving observer, and a stationary observer, moving source are different (hence, making a difference in the frequency change in the scenario I mentioned).

Well, I get that part. However, what I meant was this: The source is moving towards the observer at, let's say, 20 m/s. The observer is moving towards the source at the same speed, 20 m/s. In both cases, the observer notes a frequency different from that of the source's frequency (an...

I've tried searching the forums, but to no real avail. Here's my question (it is not really related to the Doppler Effect formulas/equations, or derivations of them): Why is the observed frequency different when you have the source moving towards the observer at a given speed, and when you...
