Snell's Law:
The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from one medium to another medium.
That is Sini/Sinr = Constant
This is known as a Snell's law.
Motion of an object in a straight line is called one dimensional motion. The location of a particle in one dimensional motion can be explained by only one variable (say x). For a p
