A sine wave is traveling to the right on a cord. The lighter line in the figure represents the shape of the cord at time t = 0; the darker line represents the shape of the cord at time t = 0.10 s. (Note that the horizontal and vertical scales are different.)
(a) What is the amplitude of the wave?
(b) What is the wavelength of the wave?
(c) What is the speed of the wave?
(d) What is the frequency of the wave?
(e) What is the period of the wave?
Could someone please help me get part e I know its 1/f which is 1/.71 which gives me 1.41 s, but its wrong, and I don't know why. Please help. Thank you.
