Given information
Given:
The plano-convex lens have Refractive index is and focal length is
Step-by-step explanation
Step 1.
Formula used:
Lens maker’s formula,
Where, is the focal length, is the radius of curvature of first surface and is radius of curvature (RoC) of second surface of the lens, and the positive signs indicates when it is in the direction of optical path, otherwise negative. And is the refractive index of the lens material.
