Intensity and phase of three sound wave reaching at some point in space is 
and 
and 
respectively. Resultant intensity at that point will be -
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Amplitude of the three sound wave would be in ratio 1 : 2 : 1. Let amplitude of first wave be A.
Figure 1
Figure 2
∴ A R = A
⇒ I R ∝ A 2 ∴ I R = I 0
