A) Two sources are vibrating in opposite phase
B) The amplitude of two sources are equal
C) At the point of observation, the amplitudes of two S.H.M. produced by two sources are equal and both the S.H.M. are along the same straight line
D) Both the sources are in the same phase
Correct Answer: C
Solution :
If two waves of nearly equal frequency superpose, they give beats if they both travel in straight line and \[{{I}_{\min }}=0\]if they have equal amplitudes.You need to login to perform this action.
