| Light as a Wave: Reflection, Diffraction, Polarization, Scattering, and Absorption |
The following demonstrations illustrate reflection, diffraction, polarization, scattering, and absorption of light. |
| Light as a Particle: Photoelectric Effect |
Planck introduced quantized energy to describe in mathematical terms the dependence on temperature and frequency of energy intensity in the spectrum of an incandescent light source. Einstein proposed particle-like light quanta, or photons, to explain the photoelectric effect. Here we demonstrate these two phenomena. |
The dual nature of light is explored. Phenomena such as reflection, diffraction, polarization, and scattering of light demonstrate its wave-like properties, while the photoelectric effect illustrates light's particle-like characteristics.
