Answer:
The distance of the first bright fringe is given as
The distance of the second dark fringe from the central bright fringe is given as
Explanation:
From the question we are told that
The slit separation distance is
The distance of the slit from the screen is
The wavelength is
For constructive interference to occur the distance between the two slit is mathematically represented as
Where m is the order of the fringe which has a value of 1 for first bright fringe
Substituting values
For destructive interference to occur the distance between the two slit is mathematically represented as
m = 2
so the formula to get the dark fringe is
Now substituting values
