The phase difference between points x and y is 180 degrees, while the phase difference between points x and z is 0 degrees, according to the established mark scheme. This is due to the relative directions of motion at specified positions rather than the angle of the sinusoidal wave. When two particles move in the same direction at the same instant, they are "in phase" with a phase difference of 0 degrees. Conversely, if they move in opposite directions, they are "out of phase" with a phase difference of 180 degrees.
PREREQUISITESStudents of physics, educators teaching wave mechanics, and anyone interested in understanding phase relationships in wave phenomena.
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:
