Question

Define a wavefront Use Huygens? geometrical construction to show
the propagation of plane wave front from a rarer medium (i) to a
denser medium (ii) undergoing refraction, hence derive Snell?s law
of refraction

Dear student
A wavefront is the locus of all points in the field of an optical
disturbance having same phase at a given instant
Medium 1 is rarer and medium 2 is denser
