Double Slits experiment

1. The problem statement, all variables and given/known data
In a double slits experiment, the intensity at the central fringe is I. What will be the intensity at the central fringe when each slit is widened 2 times?


2. Relevant equations



3. The attempt at a solution

My suggestion is that the intensity will be 2I...

Simon Bridge

But what is the reasoning?
What is the relationship between the central fringe intensity and the slit width?

I think that when the width of the each slit is doubled then the amount of light passing through will be double as well as the intensity
