Question
In the given figure, the two waves are______.
- In phase
- Out of phase
- Both a and b
- None of the above
Hint:
Two interfering waves have opposite displacements.
The correct answer is: Out of phase
In the given figure, the crests and troughs coincide with each other but are opposite in direction. Hence, the polarity of the waves is inverted in the transmission of the waves, the waves are out of phase.
Hence, (B) In phase is the right answer.
