Fringe width in Young's double slit experiment | Wave optics | Physics | Khan Academy

Fringe width is the distance between two consecutive bright spots (maximas, where constructive interference take place) or two consecutive dark spots (minimas, where destructive interference take place). Let's derive an expression for the linear and angular fringe width.

5:38 this is what i wanted... Thank you for making short videos they are really helpful... Moreover, neither the books and nor the videos explain how we get theta here. Thank you so much.

[boyuan]

Amazing dude, this is the best video I found online explaining this problem

[mysterious]

thank you so so so so much you know what i was having the same confusion that fringe width is width of the bright and and dark bands and this thing was irritating me from a very long time but thanks to you

[dharshanbabu]

Please upload for Single slit experiment Sir

[sreejithd]

Mahesh sir, you are simply amazing. I love to hear your classes 😍

[lordoftechs]

Just mind blowing sir thank you so much 😊

[ayushaggarwal]

5:00 there is a problem
You have initially taken theta from the centre of the two slits
But in the second image it is taken form is the slit 2
And it's not the same thing, trignometery won't work in first case
Or it is an assumption because slits are very close

[saumyaaryan]

sir have you made only 2 videos on ydse ?
because some of the things you are saying you have taught earlier is not under the wave optics series

[rishi]

Please make Young's single slit experiment explanation video tooo

[praneshsathishkumar]

Sir, your teaching is really incredible... I love Khan
Please upload video on Molecular Orbital theory. It would be useful if you would post in Khan Academy India(Eng) CHemistry class 11 playlist.

By the way thanks a million...

Idky but on this channel i can only understand this man!

[obsessedforgoal]

It's not कंजैकैटिव
It's कंजंक्टिव ❤❤

how small angle can be considered as arc it should be a straight line

[tanjirhabib]

Where is the link to the previous video? You should have added it in description

[anilsurjewala]
