  1. Adiffraction
  2. Binterference
  3. Creflection
  4. Dscattering

Correct answer

A. diffraction

Step-by-step solution

When a compact disc (CD) is illuminated by small source of white light, coloured bands are observed. This happens due to the phenomenon of diffraction, in which small ripples on the surface of it, break up white light into the colour of rainbow.
