What happens if the plano convex lens is placed below the plane glass plate
Answers
Answer:
The same interference pattern(newton's ring) will be observed as in the case of air medium. But the path difference is not simply 2t, it is 2nt, where n =1.333 which is the refractive index of water

Explanation:
Alternate dark and bright rings formed due to the presence of air film when the plano-convex lens is placed on the glass plate is called newtons rings.
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 replace the glass plate with a mirror then, we will not get any interference fringe because the intensity of light reflected from the mirror will be so great that it won't be visible and we will get uniform illumination.If we do this, then the interference will take place but the shape of the rings will be irregular.
