The figure represents two snaps of a travelling wave on a string of mass per unit length `mu=0.25 kg//m`. The first snap is taken at t=0 and the second is taken at `t=0.05 s`.

Determine the frequency of the wave.

Options

A. `y=10sin[2pix-(10//3)pit+(pi//6)]`
B. `y=10sin[pix-(10//3)pit+(pi//3)]`
C. `y=10sin[pix-(10//3)pit+(pi//6)]`
D. `y=10sin[2pix-(5//3)pit+(pi//3)]`

Answer

C
