Physics Question on Wave optics
Which of the following is false for interference of light?
A
Coherence of the sources is an essential condition for interference
B
The minima of the interference pattern need not be of zero intensity
C
Interference simply redistributes light energy, without destroying any of it
D
The minima of the interference pattern must always be of zero intensity
Answer
The minima of the interference pattern need not be of zero intensity
Explanation
Solution
Interference resultant intensity is maximum while at some other points it is minimum, the minima of the interference pattern must always be of zero intensity.
