In a double-slit experiment, the distance from one slit to the m = 3 bright fringe is 2,000,198.2λ. What is the distance from this bright fringe to the other, more distant slit?

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.
