wave_mechanics interference_and_superposition_of_waves Question 11
Question: If two waves having amplitudes 2A and A and same frequency and velocity, propagate in the same direction in the same phase, the resulting amplitude will be
[MP PET 1991; DPMT 1999]
Options:
A) 3A
B) $ \sqrt{5}A $
C) $ \sqrt{2}A $
D) A
Show Answer
Answer:
Correct Answer: A
Solution:
In the same phase f = 0 so resultant amplitude = $ a _{1}+a _{2}=2A+A=3A $
