Question
Indicate true or false in each of the following statements:
Two identical waves constructively interfere if their phase difference is 3 radians
Two identical waves destructively interfere if their phase difference is 7 radians
When the peaks of two identical waves coincide their sum is a wave that has twice the amplitude of each of the waves.
Two identical waves constructively interfere if the difference between the paths of the waves is one wavelength.
Destructive interference occurs when the phase difference of two otherwise identical waves is , 3, 5 etc.
Explanation / Answer
Two identical waves constructively interfere if their phase difference is 3 radians - false
Two identical waves destructively interfere if their phase difference is 7 radians - True
When the peaks of two identical waves coincide their sum is a wave that has twice the amplitude of each of the waves. - True
Two identical waves constructively interfere if the difference between the paths of the waves is one wavelength. - True
Destructive interference occurs when the phase difference of two otherwise identical waves is , 3, 5 etc. - True
