Types of Waves:
Mechanical Waves: Require a medium (e.g., sound waves, water waves, seismic waves).
Electromagnetic Waves: Do not require a medium and can travel through a vacuum (e.g., light, radio waves, X-rays).
Transverse Waves:The particles move perpendicular to the wave's direction (e.g., light waves, water waves).
Longitudinal Waves: The particles move parallel to the wave's direction (e.g., sound waves).
