### Electromagnetic Spectrum

Do we need to know the order of the electromagnetic spectrum> If so, what is it?

I'm not sure whether or not we need to know it, but I think knowing it wouldn't hurt you. Going from shorter wavelength to longer wavelength, it is
gamma ray, x-ray, ultraviolet, visible, infrared, microwave, radio

### Re: Electromagnetic Spectrum

It’s probably helpful to know some of the electromagnetic spectrum, specifically around the visible light and UV range. The order of the spectrum is expressed in terms of the wavelengths of each type of light. So from the longer wavelength (and lower energy) to shorter (and higher energy) would be:
Microwaves 1cm
Infrared 10 micrometers
Visible (Red:700nm, Violet:400nm)
UV 100nm
X-ray 1 nm

### Re: Electromagnetic Spectrum

You should have a general idea of the EM spectrum:
UV light = 100-400 nm
Visible light = 400-700 nm
Infrared = 700 nm-1 mm

### Re: Electromagnetic Spectrum

It would be good to know the order of the EM spectrum and that visible light is present from wavelengths of 400-700nm. The order from shortest to longest wavelength (conversely highest to lowest frequency): gamma rays, x-rays, ultraviolet, visible, infrared, microwave, radio.

### Re: Electromagnetic Spectrum

The EM spectrum regions should be known, but it is not neccesary to know each range of values. From highest energy (shortest wavelength) to lowest energy (highest wavelength), the spectrum is as follows: gamma rays, x-rays, ultraviolet light, visible light, infrared rays, microwaves, radio waves.
