Waves

Waves

There are 2 types of waves:

transverse waves: the disturbance is at right angle to the direction of the wave.
longitudinal waves: the disturbance is parallel to the direction of the wave. 

There are 4 important qualities associated with waves:

Speed: (symbol v, unit m/s) this is how fast the disturbance moves away from the source.
Frequency: (symbol f, unit Hz) this is the number of waves per second created by the source.
Amplitude: (symbol a, unit m) this is the maximum amount of movement of the source away from its midpoint.
Wavelength: (symbol lambda, unit m) this is the length of one wave, the distance between two crests.

To increase the speed, frequency, amplitude and wavelength…
