Draw a schematic diagram showing the (i) ground wave (ii) sky wave and (iii) space wave propagation modes for em waves.
Write the frequency range for each of the following :
(i) Standard AM broadcast (ii) television (iii) Satellite communication

Explanation

### Step-by-Step Solution

**Step 1: Draw the Schematic Diagrams**

1. **Ground Wave Propagation:**
- Draw a horizontal line representing the Earth's surface.
- Illustrate a wave starting from a transmitting antenna, propagating along the surface of the Earth.
- Show the wave bending slightly along the curvature of the Earth.
