A light source, which emits two wave lengths \lambda_1=400 nm and \lambda_2=600 nm,is used in young's double slit experiment if recorded fringe widths for \lambda_1 and \lambda_2 are \beta_1 and \beta_2 and the number of fringes for them within a distance y on one side of the central maximum are m_1 and m_2,respectively,then [JEE Adv 2014 P1]

From the central maximum 3rd maximum of \lambda_2 overlaps with 5th minimum of \lambda_1

The angular separation of fringes for \lambda_1 is grater than \lambda_2

A light source, which emits two wave lengths λ1=400 nm and λ2=600 nm,is used in young's double slit experiment if recorded fringe widths for λ1 and λ2 are β1 and β2 and the number of fringes for them within a distance y on one side of the central maximum are m1 and m2,respectively,then

[JEE Adv 2014 P1]

β2>β1
m1>m2
From the central maximum 3rd maximum of λ2 overlaps with 5th minimum of λ1
The angular separation of fringes for λ1 is grater than λ2
