A wave in a string has an amoplitude of 2cm. The wave travels in the postivei direction of x-axis with a speed of `128 ms^(-1)` and it is noted that 5 complete waves fit in 4 m length of the string. The equation describing the wave is

A

`y=(0.02)m sin(7.85x+1005t)`

B

`y=(0.02)m sin(15.7x+2010t)`

C

`y=(0.02)m sin (15.7x-2010t)`

D

`y=(0.02)m sin (7.85x-1005t)`
