Law of reflection
![[Image: image-23.png]](http://frontdesk.co.in/wp-content/uploads/2019/06/image-23.png)
θ1 = angle of incidence
θ’1 = angle of reflection.
Law of refraction (Snell’s Law) :

θ2 = angle of refraction;
μ1 = refractive index of medium 1
μ2 = refractive index of medium 2

I – Incident ray
R’ – Reflected ray
R- Refracted ray
N- Normal to the surface
I , R’ ,R ,N are in one plane
