Physics - Single Slit Differaction

Consider the following comment made by a student: "This process for determining the locations of the minima seems unnecessarily complicated. Why can't I simply continue to model the single slit as two point sources that are half the slit width apart? I already know how to determine the locations of the minima due to two point sources that are a distance a/2 apart." Does this student's proposed method for determining the locations of the higher-order minima correctly predict their locations? If not, how does it fail?

Explanation / Answer

because you see, when we are using two sources (point sources), light starts from that point itself.

but when you are uisng a single slit diffraction and calculating for a higher order minima, the distance travelled from the source of the light to the upper part of the slit and lower part of the slit is different

so for minima calculation, this difference in distance has to be considered .
