A concave spherical surface of radius of curvature 100 cm separates two media of refractive indices 1.50 and `(4)/(3)`. An object is kept in the first medium at a distance of 30 cm from the surface. Calculate the position of the image.

Explanation

To solve the problem of finding the position of the image formed by a concave spherical surface separating two media with different refractive indices, we can follow these steps:

### Step 1: Identify Given Values
- Radius of curvature (R) = -100 cm (negative for concave surface)
- Refractive index of the first medium (μ1) = 1.50
- Refractive index of the second medium (μ2) = 4/3 = 1.33
- Object distance (U) = -30 cm (negative as per sign convention for real objects)
