Answer 2

Answer:

Huygen's construction of a secondary wavelet on the passage of a plane wavefront from a denser into a rarer medium is plotted.

Explanation:

Huygen's principle is also known as Huygens–Fresnel principle, it states that each point on a given wavefront is a source of secondary wavelets or secondary disturbances.

A secondary wavelet is a wave that is caused by a disturbance that is itself a result of another disturbance. So, we can say that a disturbance causes a wave (primary wavelet), and each point on that wave is a disturbance that causes its own wave (secondary wavelets)

Hence, the secondary wavelets, as the wavefront is moving from a denser into a rarer medium are represented.
