Single slit interference and Diffraction Grating

Click For Summary
SUMMARY

The discussion focuses on the effects of modifying a double slit interference experiment by covering one slit, resulting in a transition to a single slit interference pattern. Key observations include a reduction in the number of bright fringes and a decrease in the intensity of these fringes. Additionally, when replacing a diffraction grating with a double slit setup, the interference pattern will exhibit broader and less defined fringes compared to the sharper patterns produced by the grating. The relationship between single and double slit experiments is emphasized, highlighting their interchangeable nature.

Lets say I have a double slit interference experiment set up. Now if I cover one slit what CHANGES would be observed ?

I know I would see fewer bright fringes and that the intensity of the bright fringes would fall. Is there anything else ?In a different scenario I have a diffraction grating setup. Let's say replace the grating with a double slit setup. What changes would be observed ?EDIT : In each case I am interested in changes to the interference patterns. Two observations for each would be helpful.

Here's a video (kiddy version, but does the job) explaining the double and single slit experiments.

Also, if you have a double slit experiment and cover 1 slit, you get a single slit experiment. Vice versa.
What are you asking?

What I am asking is in the above scenarios what changes would one observe in the interference patterns ?
