CH15 Mechanical Waves
 

Types of mechanical waves (»úе²¨)
Mechanical wave: disturbance that travels through a medium
Transverse wave (ºá²¨): particles oscillate perpendicular to the direction of propagation
Longitudinal wave (×ݲ¨): particles oscillate parallel to the direction of propagation
 
Periodic waves
Periodic wave: each particle undergoes a periodic motion as the wave propagates.
Sinusoidal wave (ÕýÏÒ²¨): each particle undergoes a simple harmonic motion
Wavelength: length of the smallest repeated pattern in space
