In the two-slit experiment, for the condition of bright fringes, the value of m = +2 corresponds to a path difference of λ.
true or false?

False

Explanation:

We know that if path difference is even multiple of wavelength then bright fringes are formed and if path difference is odd multiple of wavelength then dark fringes are formed .

For bright fringes

Path difference Δx = m λ

m = 0 , 2 , 4 , 6

If m = 2 then the path difference will be

Δx = 2 λ

therefore the above statement if false.

False
