What is another word for double refraction?
Pronunciation: [dˈʌbə͡l ɹɪfɹˈakʃən] (IPA) 
Double refraction is a phenomenon in which a ray of light is split into two separate rays as it passes through certain types of transparent materials. This characteristic is also known as birefringence or birrefringence. Another synonym for double refraction is diaphanous, which refers to the ability of a material to transmit light but not to scatter it. Dichroism is another synonym, which refers to the property of a material to absorb different amounts of light depending on the polarization. Lastly, polarization is another synonym for double refraction that refers to the orientation of the electric field vector of a light wave. These synonyms highlight the different aspects of double refraction and contribute to a better understanding of the phenomenon.
