A harmonic wave travels in the positive x direction at 12 m/s along a taught string. A fixed point on the string oscillates as a function of time according to the equationy = 0.0205 cos(4t)where y is the displacement in meters and the time t is in seconds(a) What is the amplitude of the wave, in meters?(b) What is the frequency of the wave, in hertz?(c) What is the wavelength of the wave, in meters?
