Physics Question on Wave optics
As a result of interference of two coherent sources of light, energy is
A
redistributed and distribution changes with time
B
decreased
C
redistributed and distribution does not vary with time
D
increased
Answer
redistributed and distribution does not vary with time
Explanation
Solution
During interference, the pattern contains both maxima and minima. This means that the energy emitted by two coherent sources are redistributed in the fringe pattern and the distribution is space dependent and time independent.
