A wave travels in a medium according to the equation of displacement given by
$y(x,t) = 0.03 \sin \pi (2t - 0.01x)$
where y and x are in meters and t in seconds. The wavelength of the wave is
Text Solution
Verified by ExpertsThe correct answer is:
A
Comparing with $y = (x,t) = a \sin(\omega t - kx)$
$k = \frac{2\pi}{\lambda} = 0.01\pi$ ⇒ ⇒ λ λ = 200 m.
