Question

derivation of Snell's law
​

Answer 1

Answer:

hi dear....

Snell's law formula is derived from Fermat's principle. Fermat's principle states that “light travels in the shortest path that takes the least time”. The normal on the surface is used to gauge the angles that the refracted ray creates at the contact point.

Answer 2

Answer:

Snell’s law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media”. Snell’s law formula is expressed as:

sinisinr=constant=μ
