Physics Question on Wave optics
In Newton ring experiment, monochromatic light is replaced by white light. Then
A
No ring pattern is observed
B
More intense bright and dark rings are observed
C
A few coloured rings with central bright spot are observed
D
A few coloured rings with central dark spot are observed
Answer
A few coloured rings with central dark spot are observed
Explanation
Solution
In Newton's ring experiment, if monochromatic light is replaced by white light then a few coloured rings with central dark spot are observed as white light is the composition of all colours
