A wave travels in a medium according to the equation of displacement given by y (x , t) = 0.03 sin `{pi (2t - 0.01 x)}` where y and x are in metres and t in seconds . The wavelength of the wave is ………. .

Options

A. 200 m
B. 100 m
C. 20 m
D. 10 m

Answer

A

Explanation

`lambda = (2pi)/(k) = (2pi)/(0.01 pi) = 200 m`
