Answer:

When light travels from one medium to another, it generally bends, or refracts. The law of refraction gives us a way of predicting the amount of bend. This law is more complicated than that for reflection, but an understanding of refraction will be necessary for our future discussion of lenses and their applications. The law of refraction is also known as Snell's Law, named for Willobrord Snell, who discovered the law in 1621.

According to the Snell's law,

  • The ratio of sine of angle of incidence to the sine of angle of refraction is constant. sine of angle of incidence(i)/sine of angle of refraction(r)=constant this constant is called refractive index(n). n=sin i/sin r
