A sunshine recorder globe is a device that provides the information about climate and weather by recording the amount of sunshine for a given location. One such globe of diameter 20 cm and refractive index 1.5 is used for the purpose. A parallel beam of light enters the globe and is refracted by the spherical surface of the globe. Determine the position of the image of the rays formed.

Explanation

To solve the problem of determining the position of the image formed by a sunshine recorder globe, we will follow these steps:

### Step 1: Identify Given Data
- Diameter of the globe (D) = 20 cm
- Radius of the globe (R) = D/2 = 10 cm
- Refractive index of the globe (n) = 1.5
- Refractive index of air (n1) = 1.0
- The object is a parallel beam of light, which means the object distance (u) = -∞ (since it is considered to be coming from a very far distance).
