18/01/2008 14:48:00 Physics 1404 Fundamental Properties of Light     Wave/Particle Duality – light is both a wave and a particle Photons – Particles of light, zero mass, but carry energy Wavelength – crest to crest, use a lambda to identify ( λ ) Period – time it takes for one set of crests to go by Frequency – number of wavelengths that go by in a given time Amplitude – the “height” of a crest Velocity=distance/time C=speed of light=300,000km/sec 5 properties:
