### memorize radiation and its frequencys?

^^ , Do you think we expected to memorize like if different radiations part of the EMspectra and its frequencies for the midterm?

You should definitely know the order of types of radiation and an approximate range of frequencies/wavelengths for most of the radiations. I'm now sure if the specific frequencies need to be memorized, but you should probably at least be able to determine that, for example, 400-700nm light is in the visible spectrum and wavelengths above/below that are for infrared/ultraviolet.

yeah we are supposed to for sure know the wavelength of visible light. Also, it's easier and recommended that you memorize the wavelengths instead of frequency because the numbers are much easier to memorize!
