Interference Demo: Double Slit

This is a demonstration of double slit interference with slit separations of 0.25 mm and 0.5 mm, with slit widths of 0.04 mm in each case. The 0.5 mm separation gives more closely spaced interference fringes than the 0.25 mm separation.

This demonstration was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

i only read it in books but now i visualized it as well
thankyou!!!

[beartimejollys_fitness]

why does no one turn on a measuring device and show the wave pattern on the wall change to particle pattern in real time? why can't i find a video with this demonstrated in real time instead of just simulated?

[ankitkeshri]

Thank You sir For practical of Interference to understand this topic more clearly and deeply.
THANKS 🙂

[PlayEase_IND]

what happened to the fact that the fringe width of dark as well as bright fringe being equal?

[dipankarsaha]

Thank you Rahul sir for forwarding it to uss

[LAZURAYOFFICIAL]

Can you explain how it's affected when observed and if the interference behaves differently if its specifically observed by a measuring instrument, or is it any object or device? Thank you.

Now find the position of 5th bright Fringe 😶

[sajanhnp]

Width Bright and dark Fringes are different why...
And also intensity is not Uniform

[AfterWorkGoGo]

Why we can't see one slit after observed?

[lakshaybhardwaj]

Why central Maxima width is double than others?

[ishan_jshi]

can you do this with a white light source

[shyamsinghkarayat]

But in interference all the fringes have same intensity.
Here the central bright is wider I think it's diffraction

Where is my commnent ?

Please, watch the video named : 'quantum mechanichs : animation explaining quantum physics.' In the first 40 seconds it explains (using marbles) Why marbles create interference pattern ( as the light do). There it is the explanation
According to the video marbles and light create same pattern. It mean both of them have same nature. If the marbles are particles same would be the light( light would have particle nature as marbles have ). So this experiment doesn't show anything. It confirms/affirms that the light is particle( like the marbles)( light has particle nature as the marbles have ). It confirms that the particles create interfered pattern as the the light do, so it mean light is a particle.

How can a single beam of light pass through two different slits at the same time???

You can give us any set of numbers. There is nothing to check here.
