OPTICS.IMages or ᰄ.com showcases optics (optics is the physics or science of light) pictures and animations created by Russell Kightley.
In these simulations, light rays (beams of light) pass through lenses, bounce off mirrors, and refract through prisms. Imaginary lenses and glass blocks change shape and refractive index. Colours add (RGB) and subtract (CMYK). Waves polarize, lasers fire, and eyes accommodate. Waves pass through slits and interfere with each other. Moving wave sources create Doppler effects. There are optical fibres and corner cubes. Videos expand to a screen-filling 4K (UHD).
ᰄ.com points to this site. ᰄ is the LEPCHA character, Gla, which resembles a pair of glasses or spectacles. See all my exotic domains.
