Question
What happens to fringe width in Young’s doubler slit experiment if it is performed inglycerine instead of air
Options
A.shrinks
B.dosppears
C.unchanged
D.enlarged
Solution
β = 
if it be performed in glycerine then
λ′ = λ/μ
β′ =
Since μ > 1
So, β′ < β (shrinks)

if it be performed in glycerine then
λ′ = λ/μ
β′ =
Since μ > 1So, β′ < β (shrinks)
