γ GAMMA RAYS
What are waves?
HX HARD X-RAYS

SX SOFT X-RAYS
EUV EXTREME ULTRAVIOLET

NUV NEAR ULTRAVIOLET

NIR NEAR INFRARED
MIR MID INFRARED

FIR FAR INFRARED
A type of wave that travels only through matter is EHF EXTREMELY HIGH FREQUENCY
called a mechanical wave.
SHF SUPER HIGH FREQUENCY
A mechanical wave forms when a source of energy UHF ULTRA HIGH FREQUENCY
causes particles of matter to vibrate.
VHF VERY HIGH FREQUENCY

HF MEDIUM FREQUENCY
LF LOW FREQUENCY

VLF VERY LOW FREQUENCY
VF/ULF VOICE FREQUENCY

SLF SUPER LOW FREQUENCY

ELF EXTREMELY LOW FREQUENCY

A type of wave that can travel through empty space Wavelength Frequency Energy
and through matter is called an electromagnetic 1pm 300 EHz 1.24 MeV
wave. 10pm 30 EHz 124 keV
100pm 3 EHz 12.4keV

1dm 3 GHz 12.4μeV
1m 300 MHz .124μeV
10m 30 MHz 124neV
An electromagnetic wave forms when a charged 100m 3 MHz 12.4neV
particle vibrates. 1km 300 kHz 1.24meV
100km 3 kHz 12.4peV
The energy that an electromagnetic wave carries is
partly electric and partly magnetic. 1Mm 3 kHz 1.24peV
