the lowest is a trough and the highest is a crest.
The trough or the valley between two waves is the lowest part of a wave. Its highest point is called the crest.
Light from the red end of the spectrum penetrates deep water better than light from the blue end of the spectrum. Evidence: Algae that live in deeper water have chlorophylls with absorbance peaks in the infra-red part of the spectrum.
The part that we call "Extremely Low Frequency Radio Waves".
The height of a wave is called the amplitude. The top of the wave is called the crest. The bottom of the wave is called the trough.The frequency of the wave is the number of wave crests passing a given point in a specific amount of time. Frequency is measured in hertz.

Homophony is where the different parts of the score move in harmony. A good example would be "Chopin's Nocturne in E, Op. 62 No. 2."* Polyphony, however, exists when the parts of the the score move completely independent of each other. "Johann Sebastian Bach's 'Fugue No.17 in A flat', from 'Das Wohltemperirte Clavier' (Part I)"**, is an example of polyphony. *http://en.wikipedia.org/wiki/Homophony **http://en.wikipedia.org/wiki/Polyphony
