Michelson – Morley Experiment :: Discussion


6.In Michaelson interferometer, the position of mirror read 0.6025mm and 0.8970mm for a pair of consecutive bright. Mean wavelength of light is 5393 Å. The difference between the two wavelengths is?
A.3 Å
B.4 Å
C.5 Å
D.6 Å
Answer:  Option  D
Explanation:

d = 0.8970 – 0.6025 = 0.2945 mm
= 2.945 X 10-4m
λ = 5893 X 10-10m
λ2–λ1 = λ22d
= 5893 X 5893 X 10-20/2 X 2.945 X 10-4
= 6 Å.
