Homework Help Overview

The discussion revolves around the double slit interference experiment and how the fringe pattern is affected when the apparatus is immersed in water. Participants are exploring the implications of changing the medium from air to water on the interference pattern observed on the screen.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are questioning how the immersion in water alters the fringe pattern, with some seeking clarification on the specifics of the setup and the parameters that may change. There is also a request for resources to better understand the topic.

Discussion Status

The conversation is ongoing, with participants expressing confusion about the question and the setup. Some guidance has been offered regarding the need to share initial thoughts for better assistance, but there is no clear consensus on the interpretation of the problem or the effects of immersion in water.

Contextual Notes

There is mention of the problem being a past year question, and participants are grappling with the assumptions regarding the light source and the conditions of the experiment.

the double slit interference experiment is set up and the fringes are displayed on screen. Then the whole apparatus is immersed in the nearest swimming pool. How does the fringe pattern change?? Which website I can get information?? Thanks.

This is a homework problem correct? (I believe I have seen it on mastering physics.)

First, if you post your thoughts on the problem to show you have made some effort you can get help in the homework help forms here. Also, if you want a good website for summaries of intro physics topics you can try:

No, it's past yr question. I dun understand wat question is ? no idea.. I oledi tried to search information on internet.. still can't get it...

when the whole apparatus place on the table, dark & light pattern display on the screen if using light source.

do u think the whole apparatus including light source is immersed in the water? or using other source?
 
picture it this way, instead of doing the experiment in air, you are doing it in water.

what is the formula concerning the fringe separation? which of the parameters in it changes when the wave is traveling in water and not in air?
