a) phase of the oscillator is same at t = 0 s and t = 2 s
b) phase of the oscillator is the same at t = 2 s and t = 6 s
c) phase of the oscillator is the same at t = 1 s and t = 7 s
d) phase of the oscillator is the same at t = 1 s and t = 5 s
Answer:
The correct options are
b) phase of the oscillator is the same at t = 2 s and t = 6 s
d) phase of the oscillator is the same at t = 1 s and t = 5 s
Explanation Two particles are said to be in same phase if the mode of vibration is same i.e., their distance will be nλ(/n=1,2,3,….)
