3. Types of Waves
3.1. Transverse Waves
3.1.1. The direction of the wave is perpendicular to the direction of the vibration of the particles
3.1.2. Example: Electromagnetic Waves
3.2. Longitudinal Waves
3.2.1. The direction of the wave is parallel to the direction of the vibration of the particles
3.2.2. Example: Sound Wave
