Double Slits experiment central fringe intensity

Click For Summary
SUMMARY

In the context of the double slits experiment, when the width of each slit is doubled, the intensity at the central fringe increases to 2I. This conclusion is based on the direct relationship between slit width and light intensity, where increasing the slit width allows more light to pass through, thereby doubling the intensity observed at the central fringe. The reasoning hinges on the principle that intensity is proportional to the amplitude of the light wave, which increases with wider slits.

PREREQUISITES
  • Understanding of wave optics principles
  • Familiarity with the double slits experiment

Homework Statement


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?


Homework Equations





The Attempt at a Solution



My suggestion is that the intensity will be 2I...
 
Physics news on Phys.org
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
