Text Solution
Verified by ExpertsThe correct answer is:
B
$y = A \sin \left(kx + \omega t \right)$
Неге $A = 0.5 \, \mathrm{m}$
$y = A \sin (kx + \omega t)$ Here A = 0.5 m $k = \frac{2 \pi}{\lambda} = \frac{2 \pi}{1} = 2 \pi \, m^{-1};$ $\omega = 2 \pi f = 4 \pi \, rad/s$ $\Rightarrow y = 0.5 \sin (2 \pi x + 4 \pi t)$
