Question
Indicate true or false in each of the following statements:
When the peaks of two identical waves coincide their sum is a wave that has four times the amplitude of each of the waves.
Constructive interference occurs when the phase difference of two otherwise identical waves is ?, 3?, 5? etc.
Two identical waves destructively interfere if their phase difference is 7? radians
Two identical waves constructively interfere if their phase difference is 2? radians
Two identical waves constructively interfere if their phase difference is 3? radians
Explanation / Answer
When the peaks of two identical waves coincide their sum is a wave that has four times the amplitude of each of the waves --FALSE
Constructive interference occurs when the phase difference of two otherwise identical waves is ?, 3?, 5? etc ---FALSE
Two identical waves destructively interfere if their phase difference is 7? radiansm---TRUE
Two identical waves constructively interfere if their phase difference is 2? radians ---TRUE
Two identical waves constructively interfere if their phase difference is 3? radians---FALSE
