Question
Here given figure (i) shows snap shot at t = T/4 and figure (ii) shows motion of particle at x = λ/4. Then the possible equations of the wave will be
Options
A.y = A sin$\left( \omega t + kx - \frac{\pi}{2} \right)$
B.y = A sin$\left( \omega t - kx + \frac{\pi}{2} \right)$
C.Both y = A cos$\left( \omega t + kx - \frac{\pi}{2} \right)$and y = A cos$\left( \omega t - kx + \frac{\pi}{2} \right)$
D.Both y = A sin$\left( \omega t + kx - \frac{\pi}{2} \right)$and y = A sin$\left( \omega t - kx + \frac{\pi}{2} \right)$
Solution
Sol.
y = Asin(ωτ – kx + π/2)
y = Asin(ωt + kx –π/2)
