### Wavelengths and their corresponding electromagnetic spectrum

Hello,
Will we need to know which wavelengths correspond to gamma, x-rays, visible light, etc..? I know that very small wavelengths are toward the gamma ray side and very large wavelengths are toward the radio waves side, but do we need to know more than that?
Thanks!!

I would say know that 400nm-700nm is visible light and then radio and infared are longer and uv, xray and gamma are shorter. knowing the order is more important than exact numbers i think.

There is another question like this already posted, according to people who already took the test you should know x rays< UV< infrareds < microwaves.
Someone also mentioned to know red light= 700nm and violet= 400nm
