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

Andreas93 [3]
<span>Well, the main point you should remember is that we only can hear  20hz that leads to T=0.05sec which means that the distance leads us to velocity x time.
When calculating, you get 330 * 0.05=16.5 .
The number which you got from the previous step has to me multiplied 4 times (4 minutes) and you will get the answer you need - </span><span>a) 66.0 m.
Do hope it will help you! Regards!</span>
