Choose the correct answer from the options given below:
Show Hint
Polychromatic light leads to the formation of colored rings due to the different wavelengths that produce constructive interference at different points.

- (A), (B), and (C) only
- (A), (B), (C), and (D)
- (B), (C), and (D) only
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
For Newton’s rings, the interference condition for constructive and destructive interference is based on the thickness t of the air film and the wavelength of light. The pattern of colored rings can only be observed if the light is polychromatic, as monochromatic light will produce a simple fringe pattern without any color.
