no they become more closer as we go away from the rad
Biprism produce straight fringe systems while Newton's rings are circular fringe patterns.

the newton ring
Biprism produce straight fringe systems while Newton's rings are circular fringe patterns.
they are formed at the point of contact of lens and glass plate
Newton's rings is a phenomenon when an interference pattern is created by the reflection of light between two surfaces. The surfaces are a spherical surface and an adjacent flat surface.
Because the intensity is maximum at the centre. Therefore the central spot is bright and not dark.
In my openion bubbles in the soap film is the real examples of it

At the point of contact the lens and the glass plate, the thickness of the film is effectively zero but due to reflection at the lower surface of air film from denser medium, an additional path difference of Lemda/2 is introduced. consequently, the centre of newton ring is dark due to destructive interference.
Newton's rings are formed due to interference between the light waves reflected from the top and bottom surfaces of the air film formed between the lens and glass sheet.
newtons ring is formed due to the consequtive circle of different radius of bright and dark in which the centre is dark
In air wedge there is uniform separation between the two slabes but in Newtons ring the thickness is varying
