A transverse wave on a string has an amplitude of 0.24 m and a frequency of 158 Hz. Consider the particle on the string at x = 0 m. It begins with a displacement of y = 0 m when t = 0 s, according to the following.
y = A sin(2πft-2πx/λ)
y = A sin(2πft+2πx/λ)
How much time passes between the first two instants when this particle has a displacement of y = 0.2 m?
Please provide answer and explanation.
