In a double-slit interference experiment, the path difference between the two waves arriving at a point on the screen is 2.5 times the wavelength . Which of the following describes the nature of the interference at this point?
A
Constructive interference resulting in a bright fringe
B
Destructive interference resulting in a dark fringe
C
Neither fully constructive nor fully destructive, intermediate intensity
D
Complete cancellation of light intensity
Correct Answer
Option C
Detailed Explanation
The path difference of 2.5 is not an integer multiple of , thus it leads to neither fully constructive nor fully destructive interference, resulting in intermediate intensity.
