A) \[{{z}_{1}}+{{z}_{2}}\]
B) \[{{z}_{2}}+{{z}_{3}}\]
C) \[{{z}_{3}}+{{z}_{1}}\]
D) \[{{z}_{1}}+{{z}_{2}}+{{z}_{3}}\]
Correct Answer: A
Solution :
[a] Standing waves are produced when two waves propagate in opposite direction. As \[{{z}_{1}}\] & \[{{z}_{2}}\] are propagating in \[+ve\,x-ax\] is \[-ve\,x-axis\] so, \[{{z}_{1}}+{{z}_{2}}\] will represent a standing wave.You need to login to perform this action.
