The focal length of an equiconvex lens is equal to radius of curvature of either surface. What is the refractive index of the material of the prism ?

Explanation

To find the refractive index of the material of an equiconvex lens where the focal length (f) is equal to the radius of curvature (R) of either surface, we can use the lens maker's formula. The lens maker's formula is given by:

\[ \frac{1}{f} = (n - 1) \left( \frac{1}{R_1} - \frac{1}{R_2} \right) \]

Where:
- \( f \) is the focal length of the lens,
