Answer:
The phase difference is
Explanation:
From the question we are told that
The distance between the slits is
The distance to the screen is
The wavelength is
The distance of the wave from the central maximum is
Generally the path difference of this waves is mathematically represented as
Here is the angle between the the line connecting the mid-point of the slits with the screen and the line connecting the mid-point of the slits to the central maximum
This implies that
=>
Substituting values into the formula for path difference
The phase difference is mathematically represented as
Substituting values
Converting to degree
the solution is subtracted by 360° in order to get the actual angle
