# Working with interference patterns

The radius of curvature of the convex surface of a planoconvex lens is 95.2cm. The lens is placed convex side down on a perfectly flat glass plate that is illuminated from above with red light having a wavelength of 580 nm. Find the diameter of the second bright ring in the interference pattern

#### Solution Preview

The experimental setup metioned in the problem corresponds to the Newton's ring experiment.

In a Newton's ring experiment, the diameter of the nth bright ring is given by the formula,

Dn = 2 * sqrt[ ( ...
