Experiments With Diffraction Gratings
- Interference and diffraction are the main phenomena which demonstrate the wave nature of the light. There are many optical devices, where these phenomena can be observed. Diffraction grating is one of them, which allows a beam of light to be resolved into different colors.
- Prominent Fraunhofer lines in the spectrum of the sun are shown, together with their corresponding wavelengths. Very pretty!
History of Optics
- Timeline of optics-related historical moments.
How Stuff Works: Light
- Seven-segment detailed explanation uses drawings and animations to show how light works and how photons are generated, with many related links.
- A book and a downloadable moire demonstration kit for printing on transparencies.
