Light
	bundles of energy called photons
	properties of
		particles
		energy
		
		each photon has a specific wavelength(pure energy)
Electromagnetic spectrum
	scale of energy of wave particles
	Short waves have more energy
		

		
Gamma rays
			

			
result from atomic reactions
			
.001 nanometer
				
nanometer = .0001 mm
			
		
X-rays
		
U-V rays
		
Visible light
			
ROY G BIV
		
Infrared (heat)
		
Radar
		
FM
		
TV
		
shortwave
		
AM
		
Visible spectrum
	the light sun makes
	
	3 things that can happen when light hits an object
	go through
	get absorbed
		absorption spectrum
			what wavelengths it will absorb
	reflect
		what we see
