Consider the three waves `z_(1), z_(2) "and" z_(3)` as
`z_(1) = A "sin"(kx - omega t)`
`z_(2) = A "sin"(kx + omega t)`
`z_(3) = A "sin"(ky - omega t)`
Which of the following represents a standing wave?

A

`z_(1)+z_(2)`

B

`z_(2)+z_(3)`

C

`z_(3)+z_(1)`

D

`z_(1)+z_(2)+z_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Waves `z_(1) and z_(2)` are travelling along the same lines in opposite direction. Hence, they produce stationary wave.
