A transverse wave propagates along the z-direction. At t = 0 s, the displacement in the y-direction is 2 cm. The displacement starts to decrease immediately after, and becomes zero for the first time at t = 0.24 s.
(a) What is the period of the wave?
(b) What is the frequency of the wave?
(c) If the wave travels 4 m along the z-direction in 0.24 s, what is the wavelength of the wave?
