The discussion revolves around the phase relationship between points x, y, and z in the context of stationary waves. The original poster attempts to clarify the phase differences they calculated and how these differ from the mark scheme's answers.
There is an ongoing exploration of the phase relationships, with participants providing insights into the definitions of being "in phase" and "out of phase." Some guidance has been offered regarding the interpretation of the problem, but multiple interpretations are still being discussed.
Participants note potential confusion between transverse stationary waves and traveling waves, as well as the importance of distinguishing between position and time in the context of wave motion.
The phase relationship pertains to the relative directions of motion at the specified positions rather than the difference in angle of the sinusoid of the stationary wave. So imagine that at some instant point x is moving upwards (or downwards), what directions would you expect the motion to be for points Y and Z?Millie Baker said:
Ah I'm sorry I didn't make it clear which part of the question I need help with! I was asking about the second part (ii), where the question is 'state the relationship between...'gneill said:
Yes, I understand. My comment addressed that. Two particles moving in the same direction at the same instant have a phase relationship of zero degrees (they are said to be "in phase"). If they move in opposite directions at the same instant then their phase relationship is 180 degrees (they are said to be "out of phase").Millie Baker said:
Ah okay, so if the wave was not reflected, would my answer be correct?CWatters said:
