The position of a transverse wave travelling in medium along positive x-axis is shown in figure at time t=0. Speed of wave is v=200 m/s
Equation of the wave is (in SI unit)
A. `y=0.04 sin 2 pi (5xx-10^(3)t)`
B. `y=0.04 sin 2 pi (10^(3) t-5xx)`
C. `y=0.04 cos 2 pi (5xx-10^(3)t)`
D. `y=0.04 cos 2 pi (10^(3) t-5xx)`
