In Young's double slit experiment, if monochromatic light used is replaced by white light, then
- A all bright fringes become white
- B all bright fringes have colours between violet and red
- C no fringes are observed
- D only central fringe is white, all other fringes are coloured
Answer & Solution
Correct Answer
(D) only central fringe is white, all other fringes are coloured
Step-by-step Solution
Detailed explanation
White light consists inumerable wavelengths. If monochromatic light is replaced by white light in Young's double slit experiment, then each wavelength form their separate interference pattern. The resultant effect of all these patterns is obtained on the screen. The waves of all…
