__Speed__


 * speed can change if it enters a new medium
 * if you assume that waves are traveling at a constant speed, then the wave length is inversely proportional to frequency
 * speed= wave length X frequency



Wavelength

• They can be measured from one point of a wave to another • The point between two waves. • Increasing the waves frequency decreases its wavelength

Frequency


 * is the number of complete cycles that pass a point in a given time.
 * Frequency is measured in cycles per second (c/sec) or Hertz (Hz)
 * The waves frequency equals the frequency of the vibrating source producing the waves



Amplitude

• A wave that is displaced from a resting position. • The more energy a wave has, the greater its amplitude is. • Ex. When you drop s pebble into a pond the wave is not very big, but when you jump into the water your wave is bigger.
