The correct answer is the peacock. The plumage found in Indian peacocks are because of the Bragg reflection phenomenon.
Explanation:
Bragg's law, or Wulff–Bragg's position, a special event of Laue diffraction, gives the plans for coherent and incoherent scattering from a crystal lattice. When X-rays are conflicted on an atom, they make the electronic cloud move as does an electromagnetic wave and it is observed in peacock.
