Answer:
Hey your answer is here!!!
Explanation:
Interference
When a thin film of oil spreads over the surface of water and it is seen in broad-day light brilliant colours are seen. These colours arise due to interference of sun-light reflected from the upper and lower surface of the film.
While bending of light rays at curvature of obstacles is called diffraction. Dispersion is splitting of white light and polarisation is the restriction of the vibrations in a transverse wave.
