Photon
Elementary particle and quantum of electromagnetic field.
Speed of Light
Photons move at 3 x 10^8 m/s in vacuum.
Energy of Photon
Quantized energy, E = hf, equals 3.98 x 10^-19 J.
Photoelectric Effect
Emission of electrons when light hits a material.
Interference
Waves overlap, creating resultant wave amplitudes.
Diffraction
Bending of waves around obstacles or apertures.
Wave-Particle Duality
Light exhibits both wave and particle properties.
Wave
A disturbance that transfers energy through space.
Isaac Newton
Physicist known for work on light and optics.
Thomas Young
Demonstrated wave nature of light through experiments.
Amplitude
Maximum extent of a wave's oscillation.
Wavelength
Distance between successive crests of a wave.
