Electromagnetic Waves • There are lots and lots of different kinds of light waves (they are not just the light we see!!!) • Called electromagnetic waves • Have electric and magnetic properties
Properties of Light Waves • Speed of a light wave will depend on what it is traveling through • Can travel fastest through empty space • Slows down in liquids and solids
Intensity • Just like sound waves, the energy of a light wave will have an affect on intensity • Higher intensity= brighter
Electromagnetic Spectrum • Light waves are separated into groups by their wavelength and frequency
Visible Light • The light we see is called visible light • All colors that we see have different wavelengths and frequencies • Think about a rainbow: what order are the colors in???
Visible Light • ROY G. BIV • Red has the longest wavelength • Violet has the shortest wavelength • Light is refracted through raindrops and separates out
Visible Light • Why is a leaf green? • Why is an apple red? • It’s all because of reflection!!!
