Electromagnetic spectrum
Cards in this deck (14)
- 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
