When a compact disc is illuminated by a source of white light, coloured lines are observed. This is due to

Options

  1. Adispersion
  2. Bdiffraction
  3. Cinterference
  4. Drefraction.

Correct answer

B. diffraction

Step-by-step solution

In compact disc colour results due to phenomenon of diffraction, in which small ripples on the surface of it break up white light into the colour of rainbow.
