A stationary wave of amplitude A is generated between the two fixed ends x = 0 and x = L. The particle at `x=(L)/(3)` is a node. There are only two particle between x`=(L)/(6) and x=(L)/(3)` which have maximum speed half of the maximum speed of the anti-node. Again there are only two particles between x= 0 and `x=(L)/(6)` which have maximum speed half of that at the antibodes. The slope of the wave function at `x=(L)/(3)` changes with respect to time according to the graph shown. The symbols `mu, omega and A` are having their usual meanings if used in calculations.

The time period of oscillations of a particle is

Options

A. T
B. 2T
C. `(T)/(2)`
D. 4T

Answer

B
