the minimal and maximal light or noise wavelengths which can be interpreted. In the human visual system, differ slightly with severity but are usually near a minimum of 380 nm and maximum of 760 nm. Rod and cone operatives additionally may be hindering aspects, and species variations are responsible for beyond human restrictions. In the human auditory system, wavelength thresholds are usually between 20 Hz and 20,000 Hz. Wavelength thresholds additionally differ within the auditory system for many species and saturations of noise.
WAVELENGTH THRESHOLDS: “A wavelength threshold is the maximum and minimum light or sound that can be perceived by an individual. “
