Physics Question on Wave optics
In interference pattern, the energy is
A
created at the maximum
B
destroyed at the minimum
C
conserved but redistributed
D
All of the above
Answer
conserved but redistributed
Explanation
Solution
In interference of light, energy is neither created nor destroyed. The energy that disappear at the points of destructive interference appears at the point of constructive interference and vice-versa. Thus, in interference of light, merely redistribution of light energy takes place.
