The Young's double slit experiment is performed with blue and with green light of wavelengths `4360 A` and `5460 A` respectively. If `X` is the distance of `4th` maximum from the central one, then :

A

`X`(blue)=`X`(green)

B

`X`(blue) gt `X` (green)

C

`X` (blue)lt`X`(green)

D

`(X("blue"))/(X("green"))=(5460)/(4360)`

Text Solution

Verified by Experts

The correct Answer is:
C
Fouth maxima will be at `y=4beta`.
`rArr y = (4lambdaD)/(d)`
as `lambda_(Green) gt lambda_(blue)`
`rArr beta_(Green)gtbeta_(blue) rArr X_(Green)gtX_(blue)`
Also get `(X(blue))/(X(green))=(4360)/(5460)`
