A wave in a string has an amplitude of `2 cm`. The wave travels in the `+ve` direction of x axis with a speed of 1`28 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 (15.7 x- 2010t) `

B

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

C

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

D

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