Laws of refraction :

 1      n = sin i /  sin r  = Refractive Index      ( Snell’s Law  )   

 2     Incident ray, Refracted ray and normal are in one plane .

   Huygens’ Principle:

"  Every point on wave-front acts as secondary source and sends secondary waves in all directions. "

Using this principle Laws of Reflection can be proved.
