törésmutatóval

Törésmutatóval refers to a numerical value that describes how much light bends or refracts when it passes from one medium to another. This phenomenon is governed by Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the two media. The refractive index of a medium is a dimensionless quantity, often denoted by the letter 'n', and it is defined as the ratio of the speed of light in a vacuum to the speed of light in that medium. A higher refractive index means that light travels slower in that medium and bends more significantly.

Different materials have different törésmutatóval values. For example, air has a refractive index very close to 1, while water has a refractive index of about 1.33, and glass typically ranges from 1.5 to 1.7. Diamond has a particularly high refractive index of around 2.42, which contributes to its sparkle. The törésmutatóval is a fundamental property in optics and is crucial for understanding and designing lenses, prisms, and other optical instruments. It is also relevant in fields like material science and astronomy. The temperature and wavelength of light can also influence the törésmutatóval of a material.
