Compute each part of following problem:
Problem: A glass cup is made to vibrate by sound. The rim of the cup has circumference 0.11m. Waves travel in a circular direction around the rim, and their speed is 700m/s. Suppose that as you go once around the rim, the wave makes three complete cycles.
Part A: What is the wavelength?
Part B: What is the frequency?
Please show me how work it out above problem.
