Question

True or False?

1) Two identical waves destructively interfere if their phase difference in pi radians

2) Constructive interference occures when the phase difference of two otherwise identical waves is 2pi or multiples thereof.

3) Two identical waves constructively interfere if their phase difference is zero.

4) Two identical waves constructively interfere if their phase difference is 3pi radians

5) When the peaks of two identical waves coincide their sum is a wave that has four times the amplitude of each of the waves.

1) True (For the phase difference of odd multiple of pi destructive interference)

2) True (For zero phase difference or the phase difference of integer multiple of 2 pi constructive interference)

3) True (For zero phase difference or the phase difference of integer multiple of 2 pi constructive interference)

4) False (Phase difference must be the integer multiple of the 2 pi)

5) False (Amplitude will be two times the amplitude of each wave)
