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, we will follow these steps:

### Step 1: Identify the given values
- Radius of curvature \( R = -100 \, \text{cm} \) (negative for concave surface)
- Refractive index of the first medium \( \mu_1 = 1.5 \)
- Refractive index of the second medium \( \mu_2 = \frac{4}{3} \)
- Object distance \( u = -30 \, \text{cm} \) (negative as per sign convention)
