call me 0.4 to 0.7 µm because I’m visibly on the spectrum

EM Waves in increasing order of frequency:

~~~

Radio Waves: Lowest frequency waves. Used to carry signals in communication industry.

Microwaves: Capable of penetrating obstacles and objects. Due to penetrating nature, they carry radar, computer data transmission etc.

Infrared Waves: IR waves of high wavelength - producing heat. IR waves of low wavelength - imaging technologies, remote controls. capturing pictures during fog, smoke etc.

Visible Light: Emitted by natural/artificial sources visible to the naked eye. (Objects are visible when they absorb light of specific wavelength and emit light of another wavelength)

Ultraviolet Waves: High frequency, low wavelength, used in studying molecular structures and help astronomers. Carcinogenic.

X-Rays: High energy waves (High frequency, low wavelength). View bone structures in the human body, X-ray therapy. Carcinogenic.

Gamma Rays: Used for medical purposes, cancer therapy. Also carcinogenic.

I still find it funny that pink is just the result of the visible spectrum of electromagnetic radiation with the absence of green. #StopGenderingEMRadiation

Adding to the list of crafting techniques for our science displays, a rope using French knitting has been artfully employed to explain electromagnetic waves. In the visible part of the spectrum, the seven colours are used. Elsewhere, we have illustrated the powers of ten to give a sense of scale. Left to right, Ben Nevis - Sherlock (radio), bumble bees (microwaves), a plant cell (infrared), bacterial cultures (visible), a water molecule (ultraviolet), the Helium atom (x-Rays) and a strange quark (gamma). At the base we have used the mnemonic 'Radioactive Mice Invade Venus Using X-Ray Guns' to help recall the order.
