🔑 Key Concepts & Definitions

• Wave: A disturbance that transfers energy through a medium or space without transporting matter.
• Mechanical Wave: A wave that requires a medium to travel, such as sound or water waves.
• Electromagnetic Wave: A wave that can propagate through a vacuum, including light, radio, and X-rays.
• Transverse Wave: A wave where particle displacement is perpendicular to the wave's direction of travel (e.g., waves on a string).
• Longitudinal Wave: A wave where particle displacement is parallel to the wave's direction (e.g., sound waves).
• Wavelength (( \lambda )): The distance between two successive crests or troughs in a wave.

📝 Essential Points

• Waves are classified into mechanical and electromagnetic based on their need for a medium.
• Mechanical waves include transverse and longitudinal types; electromagnetic waves are inherently transverse.
• The wave speed relates to frequency and wavelength via ( v = f \lambda ).
• Transverse waves involve perpendicular particle motion, while longitudinal waves involve parallel motion.
• Understanding wave classification helps predict wave behavior in different environments and applications.
