The discussion revolves around a question regarding the phase difference in a specific part of a homework assignment, particularly why it is not equal to π/2. The subject area appears to involve wave mechanics or oscillations, as indicated by the reference to phase differences and cycles.
The discussion is ongoing, with participants exploring different interpretations of the phase difference based on the diagrams provided. Some guidance has been offered regarding the relationship between the arrows and their phase difference, but no consensus has been reached regarding the correct interpretation.
There is mention of difficulty in uploading images, which may limit the clarity of the discussion. Additionally, one participant reflects on their previous understanding and acknowledges a mistake in their reasoning.
I wasn't asking why the arrows are there, that doesn't matter. I'm just asking how far apart you think they are as a number of radians, i.e. their phase difference. From your reply, you seem to think they're π apart. They're one complete cycle apart, which is 2π.kelvin macks said:i am not sure the penciled arrows is correct or not? on the top diagram in ii, both arrow at 0 and pi pointed downwards, whereas the below diagram pionted upwards. i did this beacuse i refer to the notes on other old book , but i don't know the reason why should i do this. can you expalin why?
