A sinusoidal transverse wave travels along a long stretched string. The amplitude of this wave is 0.0827 m, its frequency is 2.31 Hz, and its wavelength is 1.75 m.
(a) What is the shortest transverse distance between a maximum and a minimum of the wave?
(b) How much time is required for 70.3 cycles of the wave to pass a stationary observer?
(c) Viewing the whole wave at any instant, how many cycles are there in a 38.7-m length of string?
