How can we define Snell\'s law?

1.	How can we define Snell\'s law?
Answer» According to this rule the sine of angle of incidence to the sine of angle of refraction is always equal to the constant. This is also known as second law of refraction. Second law of refraction is known as the snells law of refraction. It states ;Sine of angle of incidence divided by sine of angle of refraction is / is equal to constant
