On the basis of Huygen's wave theory, prove Snell's law of refraction of light.

Solution

Proof of Snell's law of refraction by Huygen's wave theory:
Let speed of light in rarer medium be v1 m/s and in denser medium, be v2 m/s.
So, DD=v1t
In the same time BB=v2t
In ΔBDD sini=DDBD ....(1)
In ΔBBD sinr=BBBD ......(2)
Dividing equation (1) by equation (2), we get
sinisinr=DDBDBBBD
sinisinr=DDBB
=v1tv2t
sinisinr=v1v2=1μ2
i.e.,
1μ2=sinisinr
This is called Snell law of refraction. Hence, Snell's law is verified.
