1EM waves are..Transverse
2EM waves in orderRadio, microwave, infrared, visible, ultraviolet, x ray, gamma
3EM wave with longest wavelengthRadio
4EM wave with shortest wavelengthGamma
5Gamma raysCause mutations and cancer, which can be avoided by wearing a protective clothing and using lead shield. (Generally just avoid them.)
Can be used for chemotherapy or to sterilize food / equipment
6X RayCan cause cancer and mutations, use lead clothing / screen as protection.
Used to see the internal structure of hard objects
7UltravioletMay cause SUN burn, skin cancer, damage to surface cells. Use protective sun gear ie solar suit
Used in tanning beds, to detect false bank notes and create fluorescent objects
8Visible lightMay cause blindness in excess. Do not look directly at the sun; use sunglasses
Allows humans to see, used in photography
9Order of colors in visible light spectrumRed, orange, yellow, green, blue, indigo, violet
10Color with longest wavelength, lowest frequencyRed
11Color with shortest wavelength, highest frequencyViolet
12InfraredCauses burns, use insulating material to touch hot objects.
Used for night vision equipment and TV remote controls
13MicrowaveCould cause internal heating of body tissue. Reflect using metal screen or other protective surface.
Used to heat food, for communications sometimes TV transmissions too
14RadioMay cause health issues (unclear, but cancer, leukaemia are possibilities) and disrupt biological functions
