A wave y=a(ω t-kx) on a string meets with another wave producing a node at x=0. Then the equation of the unknown wave is
Show Hint
Nodes are formed due to complete destructive interference.

- y=a(ω t+kx)
- y=-a(ω t+kx)
- y=a(ω t-kx)
- y=-a(ω t-kx)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Node implies destructive interference.
Step 2: Waves must be opposite in phase.
Step 3: Required wave: y=-a(ω t+kx)
