If Young's double slit experiment is done with white light, which of the following statements will be true?
- A All the bright fringes will be coloured.
- B All the bright fringes will be white.
- C The central fringe will be white.
- D No stable interference pattern will be visible.
Answer & Solution
Correct Answer
(C) The central fringe will be white.
Step-by-step Solution
Detailed explanation
Young's double slit experiment with white light which consist wavelength from range \(4000 Å\) to \(7000 Å\) \(\because\) At the centre of the screen, the path difference is zero for all wavelengths. The bright fringes of these wavelengths overlap at the centre. Thus, the white…
