Snell's law tells us that,

Sine of angle of incident of light by sine of angle of refraction of light, when light travels from one medium to other, is a constant(for that mediums).

It is also related as ratio of speed of light in two mediums. This ratio is also a constant.

But, how they both are equal? How we came up with this?

are you asking how is the ratio of velocities equal to ratio of sine of angles ? – Ankit Nov 21 '20 at 12:37
Yes , how we came up with it? – GRAVITON PI Nov 21 '20 at 12:55
