Marks: +1, -0

The Young's double slit experiment is performed with blue and with green5460 Å respectively. If x is the distance of 4th maxima from the central one, then

(1990)

x (blue) =x (green)
x (blue) >x (green)
x (blue) <x (green)
x (blue)
x (green)
=
5460
4360
.

Solution:

Distance of nth maxima x=nλ

D

d

∝λ
As λb<λg
∴ x( blue $)
