's double-slit experiment. The distance between the slits is 0.1 mm and the distance between the slits and the screen is 1 m.

The formula for the distance between interference fringes in a Young's double-slit experiment is:

Δy = λD/d

Where:
Δy = distance between interference fringes
λ = wavelength of light
D = distance between slits and screen
d = distance between slits

For the 650 nm wavelength:

Δy = (650 x 10^-9 m) x (1 m) / (0.1 x 10^-3 m) = 6.5 x 10^-3 m

For the 520 nm wavelength:

Δy = (520 x 10^-9 m) x (1 m) / (0.1 x 10^-3 m) = 5.2 x 10^-3 m

Therefore, the distance between interference fringes for the 650 nm wavelength is 6.5 mm and for the 520 nm wavelength is 5.2 mm.
