B) an ellipse
C) a straight line
D) a square
Correct Answer: A
Solution :
Two simple harmonic waves of same amplitude and frequency with phase difference \[\frac{\pi }{2}\] in x and y-directions respectively are written as : \[x=a\sin \omega \,t\] ... (i) \[y=a\sin \left( \omega \,t+\frac{\pi }{2} \right)\] ... (ii)You need to login to perform this action.
