### Visible Light Spectrum... ?

For remembering the order of the visible light spectrum (ROYGBV), do we have to know the wavelengths between each color, or is knowing that visible light is between 400-700 nanometers adequate enough?

It's enough to know 400-700nm :)

We just need to know it for UV and visible light (I went to Lavelle's office hours and that was what he said :))

Does that mean we only have to know the frequency of the UV and visible lights?

Yes it would be a good idea to memorize the visible light and UV wavelengths, but don't worry too much about memorizing the wavelengths of radio waves, gamma rays, etc because it most likely won't be on the test

Basically know the following: 400-700nm = visible light, <400 nm = UV, >700 nm = IR

I was wondering the same thing since in a couple of the HW problems it ask in what spectrum a certain wavelength falls into. Thanks for the clarification! I will make sure to know the wavelength for visible, ultraviolet, and infrared. But do we also need to know the frequencies of these?
