The problem involves determining the number of fringes in a Young's Double Slit Experiment (YDSE) setup, given specific parameters such as slit separation, wavelength of light, and distance to the screen.
There is ongoing exploration of how to calculate the number of fringes based on fringe width, with some participants clarifying the distinction between bright and dark fringes. Guidance has been offered regarding the calculation method, but no consensus has been reached on the final approach.
Participants express uncertainty about applying unit values and the implications of fringe width in the context of the problem.
First calculate fringe width for given arrangementAbhimessi10 said:Homework Statement
Find number of fringes separated by 1 cm on a screen at a distance of 2mm from slits which are 0.2mm apart from each other.The wavelength of light used is 500nm.

The Attempt at a Solution
I really don't know any way to solve it.I have tried putting unit values of slit distance wavelength and screen distance but I am not sure if that can be applied here

Then by dividing 1cm by fringe width you will get the numberAbhimessi10 said:Ok then?
