The discussion revolves around the conditions under which a potential difference can be induced in a wire moving through a magnetic field, specifically focusing on the angles between the direction of motion and the magnetic field. The topic touches on concepts related to motional EMF and wave interference.
There is an active exploration of the relationship between motion and magnetic fields, with participants questioning assumptions about angles and discussing wave interference. Some guidance has been offered regarding the conditions for maximum destructive interference, but no consensus has been reached on the original question about induced potential difference.
Participants are navigating between different physics concepts, including motional EMF and wave interference, which may lead to confusion regarding definitions and setups. There is an emphasis on understanding phase differences in waves, particularly in the context of standing waves.
Nope. 0 degrees would be parallel to the magnetic field.UrbanXrisis said:So it should be 0 and 90.
Imagine (better yet, draw) two identical waves, one on top of the other. Have far would you have to slide one over to just cancel the other? (Hint: what fraction of a wavelength?)By how many degrees should two wavelengths be out of phase to produce maxium destructive interference?
You got it! How many degrees is that?UrbanXrisis said:half a wavelength?
Right again!UrbanXrisis said:so 180 degrees right?
In a standing wave, there are nodes and anti-nodes. The nodes are the places where you see minimum or no amplitude--which means maximum destructive interference; the anti-nodes are the places with maximum amplitude--thus constructive interference.UrbanXrisis said:what if two waves traveling in the same medium interfere to produce a standing wave. What is the phase diference in degrees between the two waves at a node?
Reread the thread and I'll bet you can figure it out.UrbanXrisis said:how do you find the phase difference though?
