Brechzahlen
Brechzahlen, also known as refractive indices, are a fundamental property of a material that describes how light propagates through it. Specifically, the refractive index is the ratio of the speed of light in a vacuum to the speed of light in the material. A higher refractive index indicates that light travels slower in the material, causing it to bend more when it enters or leaves the material at an angle. This bending of light is known as refraction.
The refractive index is a dimensionless quantity and is typically denoted by the symbol 'n'. The value
Brechzahlen are crucial in many optical phenomena and applications. They determine how lenses focus light, how
