Brechungsgesetz

Brechungsgesetz, also known as the law of refraction, is a fundamental principle in optics that describes how light changes direction when passing from one medium to another. It is expressed mathematically by Snell's Law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the refractive indices of the two media. This can be written as:

n1 * sin(θ1) = n2 * sin(θ2)

where n1 and n2 are the refractive indices of the first and second media, respectively, and θ1

The Brechungsgesetz is crucial in various optical phenomena, including the formation of images by lenses and
