Answer:

The postulates of Huygens's wave theory are:

  • Every particle of the medium situated on the wave-front acts as a new wave-source from which fresh waves originates. These waves are called secondary wavelets.
  • The secondary wavelets travel in the medium in all directions with the speed of the original wave in the medium.
  • The envelope of the secondary wavelets in the forward direction at any instant gives the new wave-front at that point.
