To derive the relationship between the radius of a dark Newton's ring and the radius of curvature of the lens, let's consider the interference condition for a dark ring in the Newton's rings experiment.
The condition for constructive interference in a thin film, such as the air gap between a lens and a glass plate in Newton's rings, is given by:
\[2\pi r = m\lambda\]
where:
- \(r\) is the radius of the dark
