Question

What happened to the newton's rings
when lower glass plate is rough &
not plane?​

Answer 1

Answer:

They are formed as a result of Interference between light wave reflected from upper and lower surfaces of the air films developed between the convex surface of a plano-convex lens and the plane glass plate. ... If we do this, then the interference will take place but the shape of the rings will be irregular.

hope this helps...
