### Expected to know?

Are we supposed to remember which type of wave (visible, UV, x-ray, etc) correlates with each frequency/wavelength?

Yes, but generally you should know that the visible light spectrum is 300 to 700 nm.

Thanks! But dang, we need to know all the way from y-ray to radio?

Although I don't think Lavelle will directly ask which light corresponds to which frequency or wavelength, I think it is a good idea to have a general understanding of it. It will not only help make sense of the detailed problems, but will allow you to check your answer at the end to make sure it is realistic.

I think we just need to know the specific range for visible light, and just the order in which the categories range along the spectrum!

I think it is helpful that we know

We should probably at least know the order of waves i.e. which has a shorter wavelength vs which has a longer wavelength, etc... since the photoelectric effect, which was an important part of this unit, relies on waves with short wavelength and high frequency (like UV).
Longest wavelength-----radio---microwaves---infrared---visible light---UV---X-rays---gamma rays-----Shortest wavelength
