What is refractive index of annealed glass?
The refractive index of annealed glass typically ranges from about 1.5 to 1.9, depending on its composition and the specific type of glass. Common soda-lime glass, for example, has a refractive index around 1.5, while specialty glasses, such as crown glass, may have slightly higher values. This optical property is crucial in applications like optics and materials science, influencing how light interacts with the glass.
