Question

prove the laws of refraction on the basis of hugens wave theory of light​

Answer 1

Answer:

Snell's law of refraction using Huygen's Principle:

Consider a plane wavefront AB incident on a surface PQ separating two media 1 and 2.

The medium 1 is a rarer medium of refractive index

n

1

in which light travels with a velocity

C

1

. The medium 2 is denser medium of refractive index

n

2

in which light travels with a velocity

C

2

.

The angle between the incident ray FA and the normal NA at the point of incidence A is equal toi.

The angle is also equal to the angle between the incident plane wavefront

BA

and the surface of separation PQ.

So ∠BAD is the angle of incidence of the incident plane wavefront AB.

Similarly, the angle between the refracted wavefront and the surface of separation PQ is equal to the angle of refraction r.

Answer 2

Answer:

According to Huygens’ principle, secondary wavelets will originate from A1 and will spread over a hemisphere in glass.

All the rays between AA1 and BB1 will reach XY and spread over the hemispheres of increasing radii in glass. The surface of tangency of all such hemispheres is RB1. This gives rise to refracted wave front B1R in glass.
