Question

In a YDSE set up the separation between the slits is 3 10⁻³ ~m . The distance between the slits and the screen is 1.5 m . Light of wavelength in the visible range ( 4000 Å-8000 Å ) is allowed to fall on the slits. The wave length in the visible region that will be present on the screen at a distance of 1.5 10⁻³ ~m from central maxima is

Quantrex Academy · Accepted Answer

Correct answer: D. 7500 Å

Here the position y on the screen will correspond to maxima. aligned & y= n D d & = 30,000 n when n=1,2,3,4, aligned
