Phase difference/ path difference Watch
b) path differences give rise to phase differences. By how much do the following change the phase difference?
(i) 1 wavelength
(iii) 3 wavelength/4
c) What path differences would give the following phase differences?
(i) 90 degrees
(ii) 120 degrees
Any help would be great!!
so... if difference in path (Dl) = 0λ
then difference in phase (Dφ) = 0 degrees
if difference in path = 100λ
then difference in phase = 36000 degrees
