In Young double slit experiment, if white light is used____________________?
Correct answer: B. coloured fringes will be seen
- A. alternate dark and bright fringes will be seen
- B. coloured fringes will be seen
- C. no interference fringes will be seen
- D. impossible to predict
Explanation
Different colours in white light have different wavelengths, so their bright and dark fringes occur at different positions, producing coloured fringes near the central white fringe. Option a is a common choice because each individual colour does form alternate bright and dark fringes, but the combined pattern is coloured rather than simply alternating light and dark.

About Superposition and Interference
Superposition states that overlapping waves produce a resultant displacement equal to the algebraic sum of their individual displacements. Interference covers constructive and destructive interference, phase difference, path difference, coherent sources, and conditions for maxima and minima. It differs from diffraction, which involves spreading around openings or obstacles.
