Double refraction #Shorts #physics #science #optic #refraction #experiment #experiments #notes #art Double refraction in Icelandic spar : the speed of light in a crystal depends on the polarization - the refractive index differs depending on the orientation of the polarization of the light passing through it. When light propagates in an arbitrary direction relative to the optical axis , two beams are observed that have different polarization. One of the theories that can explain this phenomenon is that the alternating electromagnetic field of a light wave causes electrons in a substance to oscillate, which affect the propagation of light. In some substances, vibrational processes occur in certain directions. #physicsfun #light #amazing #interesting #jurij0001 #YuriKovalenok
