Frequency & Wavelength such as this picture Examples of Frequency & Wavelength
 * media type="custom" key="5853005" align="center"
 * Frequency: number of complete cycles in a given time
 * measured in cycles per sec (Hertz)

=1. Amplitude : The amplitude of a wave is the max displacement from the rest position. =


 * EX: the move energy of a wave has greater amplitude**

**//Speed//**
 * **//If waves are traveling at a Constant Speed, then wavelength is inversely proportional to frequency//**
 * //{speed = wavelength * frequency}//**



__Wavelength__


 * *Wavelength is the distance between a point on one wave and the same point on the next cycle wave.

EX: Increasing the Frequency of a wave decreases its wavelength.
