'Greater the height of T.V. transmitting antenna, greater is its range.'' Prove.

Explanation

To prove that "greater the height of T.V. transmitting antenna, greater is its range," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Setup**:
- Consider the Earth as a sphere with radius \( R \).
- Let \( H \) be the height of the transmitting antenna above the Earth's surface.
- The point where the signal from the antenna touches the Earth is point B.
