I think it would be useful to remember the order of the wavelength classifications from largest to smallest energy, but not necessary to remember the exact length of each category, such as 10^-12
I am going to try and remember the ranges they are in. For example, that x-rays are 10^-9 m. There was a question on the homework that asked to identify what spectrum the light was in based on its wavelength.
No, I don't think the specific wavelengths are necessary. Rather, maybe just knowing the spectrum in order of increasing wavelength/frequency might be helpful since you can check if your answers are reasonable. Also, knowing that visible light is between 400-900 nm is important.

I did some research that said infrared radiation is emitted when objects are hot but not hot enough to emit visible light. This makes sense because infrared radiation in just below visible light on the EMR spectrum, with red having the lowest energy of the different types of visible light. Some examples include burning charcoal or a radiator emitting warmth.
