For a given point on a string, a peak of a harmonic wave is observed to pass every 0.2 s. The distance between peaks is 2.0 m. The height of the peak is 0.07 m. Assume that the wave is moving to the right. (i) What is the one-dimensional equation describing this wave (assume that at t = 0 the wave has its first peak)? (i) What is the phase speed of the wave? (ii) The string has a linear density u = 0.05 kgm-1. What is the %3D tension in the string?

For a given point on a string, a peak of a harmonic wave is
observed to pass every 0.2 s. The distance between peaks is
2.0 m. The height of the peak is 0.07 m. Assume that the wave is
moving to the right.
(i)
What is the one-dimensional equation describing this wave
(assume that at t = 0 the wave has its first peak)?
(ii)
What is the phase speed of the wave?
(iii)
The string has a linear density u = 0.05 kgm-1. What is the
tension in the string?
