Explain surface wave propagation of radio waves. Why does this method fail in case of short waves ?

Explanation

### Step-by-Step Solution:

1. **Definition of Surface Wave Propagation**:
- Surface wave propagation, also known as ground wave propagation, refers to the transmission of radio waves that travel along the surface of the Earth. This method is particularly effective for low-frequency radio waves.

2. **Mechanism of Surface Wave Propagation**:
- In surface wave propagation, radio waves emitted from a transmitting antenna travel close to the Earth's surface. As these waves propagate, they follow the curvature of the Earth due to the influence of the ground. This allows the waves to reach receiving antennas that are located at a distance from the transmitter.
