In Young’s double-slit experiment, an interference pattern is obtained on a screen by a light of wavelength 6000 Å, coming from the coherent sources S 1 and S 2 . At certain point P on the screen third dark fringe is formed. Then the path difference S 1 P – S 2 P in microns is
Text Solution
Verified by ExpertsThe correct answer is:
B
For dark fringe at P
Here n =3 and λ λ = 6000
