Answer 2

d)square root of natural number

Explanation:

• When the plano-convex lens is placed on a flat glass plate with a convex surface, the thickness  between the lens and the glass plate increases gradually.
• The thickness of the  air film is almost zero at the O junction and gradually increases in  subsequent processes. Along the edge of the lens. When monochromatic light normally strikes the lens,film can be seen in incident light alternating between bright and dark concentric circles.
• Around  contacts.This ring got its name because it was first discovered by Sir Isaac Newton. Newton's ring.consider the beam Monochromatic light usually falls on the top surface of the air film. Beam partially hit   reflection and partial refraction.
• Light rays refracted by the air film are also partially reflected. the bottom of the film. Generates two reflected beams, top and bottom  Film, Consistently and Constructively or Destructively Interfering
