Two waves have equations :
y 1 = a sin 
If the amplitude of the resultant wave is equal to the amplitude of each of superimposing waves, then what will be the phase differences between them?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Amplitude of the resultant wave
∴ 
Given , A = a 1 = a 2 = a (say), then
a 2 = 2a 2 + 2a 2 cos Δφ
so a 2 = 2a 2 (1+cos Δφ )
So 1+ cos Δφ = 
So 
So
