Which waves constitude amplitude-modulated band?

Explanation

To solve the question "Which waves constitute amplitude-modulated band?", we can break down the answer into clear steps:

### Step-by-Step Solution:

1. **Understanding Amplitude Modulation (AM)**:
- Amplitude modulation is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In AM, the amplitude of the carrier wave is varied in proportion to the waveform being sent.

2. **Identifying the Frequency Range**:
