Complete the following sentence :
A transverse wave is composed of crest and ……………………

Explanation

To complete the sentence, we need to identify the components of a transverse wave.

1. **Understanding Transverse Waves**: A transverse wave is a type of wave where the particle displacement is perpendicular to the direction of wave propagation. This means that as the wave travels, the particles of the medium move up and down while the wave itself moves forward.

2. **Identifying Components**: In a transverse wave, there are two main components:
- The **crest**, which is the highest point of the wave.
- The **trough**, which is the lowest point of the wave.
