Term: Wavelength
Definition (Myers):The distance from the peak of one light or sound wave to the peak of the next. Electromagnetic wavelengths vary from the short blips of cosmic rays to the long pulses of radio transmission. 1
Definition (alternative): Wavelength is the distance between repeating units of a propagating wave of a given frequency. It is commonly designated by the Greek letter lambda (λ). Examples of wave like phenomena are light, water waves, and sound waves. 2 (Link)
Contextual explanation: Wavelength is ien a wave, properties vary with position. For example, in a sound wave the air pressure oscillates, while in light and other electromagnetic radiation the strength of the electric and the magnetic field vary. Also short wavelength is equal to high frequency, and long wavelength is equal to low frequency. Although great amplitude represents bright color, and loud sounds. Furthermore, small amplitude is dull colors, and soft sounds.
