In the double-slit interference experiment, the distance of the nth-maximum from the center of the screen is given by
where
is the wavelength
D is the distance between the screen and the slits
d is the distance between the slits
In our problem,
By applying the previous formula, we can calculate the distance of the 4th maximum from the center of the screen:
Similarly, the distance of the 8th- maximum is
Therefore, the distance between the two maxima is
