## Snell's law of refraction - Ray Optics, Physics - eSaral

Hey, do you want to learn about Snell's law of refraction? If yes. Then keep reading. Snell’s Law: For any two media and for the light of a given wavelength, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. $\frac{\operatorname{Sin} \mathrm{i}}{\operatorname{Sin} \mathrm{r}}=$ constant, Where i = incidence angle r = refraction angle. The incident ray, the refracted ray, and the normal at the incident point all lie in the same plane. Frequency ...
