Next, determine the frequency. Think about how far apart each wave crest is. Definitions by the largest Idiom Dictionary. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, troughs, or zero crossings, and is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. Examples of wavelength in the following topics: Dispersion: Rainbows and Prisims. The wavelength of light determines its color, and the wavelength of sound determines the pitch. Different types of electromagnetic radiation can be arranged according to their wavelength and frequency values. Optical Channel The wavelength allocation for a particular signal. The wavelength of audible sound range from about 17 mm to 17 m. Wavelengths of audible sound are much longer than those of visible light.
