Question

What is the range of frequencies of visible light?

Answer 1

Visible light has wavelengths from 400 nm to 700 nm. Using \[\ce{\nu=\frac{c}{\lambda}}\], its frequency range is approximately \[\ce{4.3\times10^{14},\text{Hz}}\] to \[\ce{7.5\times10^{14},\text{Hz}}\]. Thus, the frequency range of visible light is \[\ce{4.3\times10^{14}\text{--}7.5\times10^{14},\text{Hz}}\].
