When exposed to sunlight, thin films of oil on water often exhibit brilliant colours due to the phenomenon of

Options

  1. Ainterference
  2. Bdiffraction
  3. Cdispersion
  4. Dpolarisation.

Correct answer

A. interference

Step-by-step solution

The colour in the oil film is formed due to interference of sunlight where the colour of the film will depend upon the thickness and the angle of inclination.
