Three waves of equal frequency having amplitudes 
, 
marrive at a given point with successive phase difference of 
, the amplitude of the resulting wave (in 
) is given by
Text Solution
Verified by ExpertsThe correct answer is:
B
Given, the amplitudes of the waves are
and the phase difference between 1st and 2nd wave is 
and that between 2 nd and 3rd wave is 
.
Therefore, phase difference between 1st and 3rd is 
. Combining 1st with 3rd, their resultant amplitude is given by
or 
Now combining this with 2nd wave we have the resultant amplitude
or 
Hence, amplitude of resulting wave is 
.
