A harmonic wave moving in the positive x direction has an amplitude of 4.4 cm, a speed of 41.0 cm/s, and a wavelength of 45.0 cm. Assume that the displacement is zero at x = 0 and t = 0.
Calculate the displacement (in cm) due to the wave at x = 0.0 cm, t = 2.0 s.
Calculate the displacement due to the wave at x = 10.0 cm, t = 20.0 s.
