Question
Indicate whether the statement is true or false
Two identical waves destructively interfere if their path difference is zero.
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 5 radians
When the peaks of two identical waves coincide their sum is a wave that has four times the amplitude of each of the waves.
Two identical waves constructively interfere if the difference between the paths of the waves is one wavelength.
Explanation / Answer
two identical waves destructively interfere if their path difference is odd multipal of half of wavelength so first statement is wrong
for constructive interferance phase difference have to be even multipal of pie so second statement is also wrong
for destructive interferance phase difference have to odd multipal of pie so third statement is correct
if two identical waves coincide their sum is a wave that has twise times the amplitude of each of the wave so fourth statement is wrong
two identical waves constructively interfere if the path difference is even multipal of half of wavelength so final statement is correct
