A) \[\text{ }\!\!\pi\!\!\text{ /4}\]
B) \[\text{ }\!\!\pi\!\!\text{ }\]
C) \[\text{ }\!\!\pi\!\!\text{ /8}\]
D) \[\text{ }\!\!\pi\!\!\text{ /2}\]
Correct Answer: D
Solution :
Waves equations are \[{{y}_{1}}=a\sin (\omega t-kx)\] and \[{{y}_{2}}=a\cos \,(\omega t-kx)\] \[{{y}_{2}}=a\cos \,\left( \omega t-kx+\frac{\pi }{2} \right)\] \[\therefore \] Phase difference between the waves \[=\frac{\pi }{2}\]You need to login to perform this action.
