Waves

Post Number: #1  Postby Jessica » April 13th, 2012, 7:06 pm

Waves

All waves are travelling disturbances that carry energy from place to place.


Mechanical Waves

Transverse - a wave in which the direction of vibration of the particles is perpendicular to direction in which the wave travels

Longitudinal - a wave in which the direction of vibration of the particles is parallel to direction in which the wave travels



Characteristics

Wave length (λ) - the shortest distance between repeating points on a wave. Unit: meters (base, can be centimeters, nanometers etc)

Frequency (f) - the number of cycles in a given amount of time. Unit: Hertz (Hz)

Amplitude (A) - the maximum displacement of a wave particle from equilibrium. Unit: meters (base, can be centimeters, nanometers etc)

Period (T) - the time it takes one wave to go through one vibration


Wave speed/velocity:
V = λ/T = λf
