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
