How would the angular separation of interference bands in Young's double slit experment change when the distance of separation between the slits and the screen is doubled?

Explanation

`beta_(1)=(D_(1)lamda)/(d_(1)),beta_(2)=(D_(2)lamda)/(d_(2))`
`D_(1)=D,D_(2)=2D`
`d_(1)=d,d_(2)=2d`
`:.beta_(2)=(2Dxxlamda)/(2d)=(D lamda)/d=beta_(1)" "` i.e. `beta_(1)=beta_(2)`
