Waves

- Wave is a traveling disturbance from a vibrating source.

- Carries energy in the direction of its propagation.

- It is a mean of energy transfer through vibration.

Crest - maximum upward movement of wave from rest

Trough - maximum downward movement of wave from rest

Amplitude - maximum diplacement of particle from rest to crest or trough

Wavelength - Length of one complete wave cycle

One complete vibration Cycle of wave

Types of Wave

Differentiation

	Transverse Waves	Longitudinal Waves
Wave movement	Left to right	Left to right
Movement of particles in medium	Perpendicular to wave	Parallal to wave
Waves travelin the form of	Crests and troughs	Condensations and Rarefractions
One wave consists of	One crest and one trough	One condensation and one rarefraction
Examples	Light waves Electromagnetic waves	Sound waves
