A sinusoidal wave of wavelength 1.91 m and amplitude 0.159 m travels with a speed of 0.743 m/s on a string. Initially, the left end of the string is at the origin and the wave moves from left to right.
a) Find its frequency.
Answer in units of Hz
b) Find its angular frequency.
Answer in units of s-1
c) Find its angular wave number.
Answer in units of m?1 d)What is the maximum speed of any point on the string? Answer in units of m/s
