a. if the phase difference between them is an even multiple of π
b. if the path difference is an even multiple of (λ / 2)
c. if the time interval is an even multiple of (T/ 2)
d. All of the above


ANSWER: See Answer
 
Two vibrating particle are said to be in same phase, if the phase difference between them is an even multiple of π or path difference is an even multiple of (λ / 2) or time interval is an even multiple of (T/ 2).
