Answer:
x' =2000201.2 λ
Explanation:
Given that
m = 3
We know that path difference is given as
Δx = m λ
x' - x = m λ
Given that x= 2,000,198.2λ
x'=Distance between far distance slits
x=Distance between near distance slits
Now by putting the values in the above equation e get
x' = 2,000,198.2λ + 3 λ
x' =2000201.2 λ
Therefore the answer will be 2000201.2 λ.
