Refraction by Spherical Surfaces: Practice Problem & Solution

A plano-convex lens of unknown material and unknown focal length is given. With the help of a spherometer we can measure the, (2020-Covid)
Radius of curvature of the curved surface
Aperture of the lens
Refractive index of the material
Focal length of the lens

Solution Explained:

To solve this problem, we apply the core principles of Refraction by Spherical Surfaces. Understanding the underlying formula is key to arriving at the correct answer below:

A spherometer is an instrument specifically designed to measure the radius of curvature of spherical surfaces. Therefore, it can be used to measure the radius of curvature of the curved surface of the plano-convex lens.
