wave_mechanics interference_and_superposition_of_waves Question 1
Question: There is a destructive interference between the two waves of wavelength l coming from two different paths at a point. To get maximum sound or constructive interference at that point, the path of one wave is to be increased by
[MP PET 1985]
Options:
A) $ \frac{\lambda }{4} $
B) $ \frac{\lambda }{2} $
C) $ \frac{3\lambda }{4} $
D) $ \lambda $
Show Answer
Answer:
Correct Answer: B
Solution:
With path difference$ \frac{\lambda }{2} $ , waves are out of phase at the point of observation.
