Question

Where is visible light located on the electromagnetic spectrum?

Answer 1

Around `"400 - 700 nm"` wavelength, or a frequency of `7.50 xx 10^(14) - 4.28 xx 10^(14) "s"^(-1)`, or a wavenumber of `25000 - "14286 cm"^(-1)`:

Here, `color(red)("red")` has the longest wavelength and `color(purple)("violet")` has the shortest wavelength.

Do you know the 7-letter mnemonic for the prominent colors in the visible spectrum?
