Q1). For a denser medium, angle of incidence in rarer medium is 60 degrees and the angle of refraction in denser medium is 45 degrees. Calculate the refractive index of the medium.

Q2). A glass slab made of material of refractive index n1 is kept in a medium of refractive index n2. A light ray is incident on the slab. Complete the path of rays of light emerging from the glass slab if:
a) n1>n2
b) n1=n2
c) n1
