Question

A circular wave travels outward from the origin. at one instant of time, the phase at r1 = 12.0 cm is 0rad and the phase at r2 = 75.0 cm is 3πrad .

Answer 1

A circular wave travels outward from the origin. The phase at r1 = 12.0 cm is 0 rad and the phase at r2 = 75.0 cm is 3π rad. The phase difference between the two points is 3π rad.

Step-by-step explanation:

A circular wave travels outward from the origin. The phase at r1 = 12.0 cm is 0 rad and the phase at r2 = 75.0 cm is 3π rad. To find the phase difference between the two points, we can use the formula:

Phase Difference = (Phase at r2) - (Phase at r1)

Phase Difference = 3π rad - 0 rad = 3π rad
