A harmonic wave travels in the positive x-direction at 11 m/s along a taught string. A fixed point on the string oscillates as a function of time according to the equation

y= 0.037 cos(2t)

where y is the displacement in meters and the time t is in seconds.

Part (a) What is the amplitude of the wave, in meters?

Part (b) What is the frequency of the wave, in Hertz?
