In Young's double slit experiment is performed with blue and with green light of wavelengths 4360 Å and 5460 A respectively. If x is the distance of 4^(th) maxima from the central one, then.....

Answer»

X (BLUE) = x (GREEN)
x(blue) `gt` x (green)
x (blue) `lt` x (green)
`(x("blue"))/(x("green"))=(5460)/(4360)`

SOLUTION :DISTANCE of `n^(th)` Maxima `x=nlambda(D)/(d)`
`:.xprop lambda`
`:. Lambda_("blue") lt lambda_("green") "" :. X_("blue") le x_("green")`
