What is the maximum frequency of visible light in hertz?
Nataliya [291]
All frequencies of light in hertz are in between
Red = 4 * 10 ^{14} Hz and
Violet = 8 * 10 ^{14} Hz

Light with a lower frequency than 4 * 10^14 Hz, are called infrared and can't be seen by human eye. Light with a higher frequency than 8 * 10^14 Hz, are called ultraviolet and can't bee seen by human eye. 

Therefore, the maximum frequency of visible light in Hz, is  8 * 10^14 Hz
