Mechanical Waves

Short Definition

Mechanical waves are disturbances that travel through a medium, transferring energy without the transfer of matter.

Detailed Explanation

Mechanical waves require a medium (solid, liquid, or gas) to propagate. They are classified into longitudinal and transverse waves depending on the direction of particle vibration relative to wave propagation.

Types of Mechanical Waves

• Longitudinal Waves: Particle vibration is parallel to wave direction (e.g., sound waves).
• Transverse Waves: Particle vibration is perpendicular to wave direction (e.g., waves on a string).

Wave Properties

• Wavelength (λ)
• Frequency (f)
• Speed (v)
• Amplitude (A)
• Energy carried by waves

Importance

Mechanical waves explain sound, vibrations, seismic activity, and are fundamental in engineering and communication technologies.
