Question
In Young′s double slit experiment, the slits are 2 mm apart and are illuminated by photons of two wavelengths λ1 = 12000
and λ2 = 10000. At what minimum distance from the common central bright fringe on the screen 2 m from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other ?
and λ2 = 10000. At what minimum distance from the common central bright fringe on the screen 2 m from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other ?Options
A.3 mm
B.8 mm
C.6 mm
D.4 mm
Solution
According to question n1λ1 = n2λ2
So
so minimum n1 and n2 are 5 and 6 respectively.
Xmin =
= 6 × 10-3 m = 6 mm
So
so minimum n1 and n2 are 5 and 6 respectively.
Xmin =
= 6 × 10-3 m = 6 mm
