The radius of curvature of the convex surface of a thin plano-convex lens is 12 cm, and the refractive index of its material is 1.6. What is the power of lens ?

Explanation

To find the power of the thin plano-convex lens, we will follow these steps:

### Step 1: Identify the given values
- Radius of curvature of the convex surface (R1) = 12 cm
- Radius of curvature of the plane surface (R2) = ∞ (infinity)
- Refractive index (μ) = 1.6

### Step 2: Use the lens maker's formula
