When a compact disc(CD) is illuminated by small source of white light coloured bands are observed. This is due to
- A diffraction
- B interference
- C reflection
- D scattering
Answer & Solution
Correct Answer
(A) diffraction
Step-by-step Solution
Detailed explanation
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.
