I've attached the multiple choice question.
The first time round that I did it, I simply just did a phase shift of the whole graph by pi. Basically I just translated the whole graph by pi, resulting in option (D).
However, it later came to my attention that by continuing to draw the waveform in the medium itself and simply reflecting it just like a mirror, you will get the reflected and pi phase shift, but this gets the answer as option (B), which is still wrong.
Working backward from the answer, it seems as though i have to use both the reflecting and afterwards translating the whole graph by pi in order to get the answer, which is option (C)?
Can anyone explain the mechanics behind the methods of what I'm doing? Or perhaps just an explanation to better understand the mechanics of the wave reflection?
Thank you!
