Sir diffraction of light occur when light hit the ends of the slit then why here every light bends at an angle theeta even they are passing between the slits,not hitting the slits
Good question. Though these rays are not touching slit, they are very close to the slit(as the slit width is very small say in micrometers) where influence(for very short distance) of atoms of the slit is present. Because of interaction of electric field of atoms of slit and electric field in wave, diffraction occurs. This is quantum mechanical phenomenon. If the slit width is large, central rays will not diffract and will go straight.
@@SSPhysics Sir , but according to Huygens's principle each point in the plane of the slit will behave as a secondary wavelet and therefore light goes in all possible directions so that's why rays bend at an angle of theta ?
way in which u have explain with phraser diagram that is very useful to me, sir I am requesting to u please, explain "freunhaffer diffraction at double slit" like this
Sr in this video you showed that the rays diffracted downword at the point A. But we know diffracted rays go along the geometrical shadow region.but here the rays diffracted towards the eluminated region.how could it be possible?
@@chandrasekharbehera8796 Here, the diffraction effect is shown at a single point on the screen and that is why we are considering all the wavefronts/rays which are propagating parallel to each other( Assuming refraction of all the parallel rays is the same throughout) which helps us reach the conclusion that the point is of minimum intensity( If we assume that the total path difference is equal to the wavelength of the light incident on the slit)
+SAISARIKA DEVISETTY Thank you for watching and commenting. You want a short explanation of double slit diffraction or a detailed explanation as in above video?
Hello, I am Assistant Prof. at an engineering college in Pune. I make the videos in my spare time on Engineering Physics. It takes lot of time to make good video because of the animation, recording and editing etc. Also I alone work to make the video. Presently I am making videos on topics which i teach to engineering students(Pune University). Sorry but for other topics it will take time(few months)
+Sheikh Azhar In top figure only one lende is shown. First lens is not shown. But it is there, which gives parallel rays which get incident on the slit.
Very nice! It is the clearest video on youtube on this topic.
I am struggling for 2 hour with my book for this topic and from your video I learn the concept in 16 minutes.
Thanks a lot!
Same
The way you explained the phasors was really awesome. Thanks. Just what I needed.
Thanks for your appreciation. Please like the video. Subscribe and watch other videos from SS Physics channel
best explained
Sir aap to upcoming physics wallah ho....👍
Nice explanation sir👍👍
Just one word I can say " awesome "
Really excellent explanation with phasor diagram
This was beautiful
Superb explanation !!!!! Zabardast!!!!
awsome great explaination its now easy to que based on diffraction thanks a lot sirrrrrrr love from bottom of heart to physicsss
simply super explanation about phasors.thank u sir
Thank you Sir,
Thank you so much!
Superb.. Really 🙂
Very nice and lucid explanation.
Thank you very much, Sir.
Good sir....
Sir bohot detail mai explain kiya ,aur easy way say ,ty sir
Very Nice Explanation. Very Good. Maintain it Sir.
Really very detailed concept given by u
Crystal clear concept
Thanks 😬
literallly amazing video
perfect explaination ! concept is much clear now . Thanks
Thanks. Please refer SS Physics channel to your friends.
excellent
Thanks to clear my dout about thik topic
wow i can understand this subject now
Thanks a lot you have got a new subscriber,awesome animations
very nice explaination sir thank you
Done with detailed explanation (step by step). Good work. Thanks a lot. Please carry on your hard work.
clear and detailed explanation. very helpful. perfect pace . ty :)
+tamil selvi
Thanks
Awesome 😁😁😁
Thank u sir very very nice explaination and representation...add more videos please on interference and diffraction
Awesomeness.great sir..Plz more videos

Yes. You are right.
Awesome, I didn't find this explanation till now, keep going ✌️
nice video
Thank u sir very well explained
Best
sir make a video on diffraction due to double slit btw your explanation is perfect
satisfied by the video but at the same time i was annoyed by the interrupting adds which were coming in between.
Absolutely amazing! Thanks for the help!
Welcome. Please recommend to your friends.
Sir very good way
Nice
Very useful video
Thank you Prof. I'm from Malaysia and this lecture help me a lot
Amazing video - Thanks keep it up
+Meow karia
Thanks for encouragement.
Please make video on diffraction through double and triple slit.
path difference between 1st and 3rd ray, two consecutive rays ka k brabr ho ga ya zyada ho ga?
I get it
Thank you sir I liked& subscribed
Thanks sir I got it
understood clearly
Thanks
I'm a bit confused
But I'll keep watching this... hopefully I'll get it
Tq soo much
Awesome!
Very detailed explanation sir. Loved it!
Thanks Siddhant for your comment. Share this to all your engineering friends.
nice explanatuion
sir,please add video on topic zone plate
Sir explanation is very good....but you did a mistake in equation number...........finally......video is very clear full
Pavan Reddy Medapati
Thanks for the comment. Which equation you are talking about? And what mistake?
Sir equation number 1 you considered 2times......
Pavan Reddy Medapati
Yes you are right..
You can ignore first equation number.
Can u prepare video for fraunhofer diffraction due to double silt
BURA SAIKUMAR
Sure. But it will take time.
+SS Physics kb ayega???
way in which u have explain with phraser diagram that is very useful to me, sir I am requesting to u please, explain "freunhaffer diffraction at double slit" like this
Helped me a lot
Keep making more videos and helping students.
Thank you very much
Sr in this video you showed that the rays diffracted downword at the point A. But we know diffracted rays go along the geometrical shadow region.but here the rays diffracted towards the eluminated region.how could it be possible?
Here slit width is shown big for convenience. That's why it appears like that.
But sir how the rays from A&B will be parallel. If the slit width is very small,then also we can show one ray going upward and another downwards.
When single ray passes through slit party it get diffracted upward, partly downward and partly goes straight i.e. parallel or undiffracted.

@@chandrasekharbehera8796 The effect on all points of the screen is not being considered for simplicity.
Sir what about secondary maxima and minima ??
GREAT
Helped me alot...
Nice nice

Add videos on nano particle
Dear students I want your feedback about videos on SS Physics. Like speed of explanation, video sound, method used(ppt), animation etc.
Can u add a video of Fraunhofer double slit experiment
all things mentioned above are perfect
I liked your animation, and style of explanation.......
'
thank you
very much.......

Derivatives k bare me kuch puchna hai
Reply me if Yes
The video is very good...Can you explain Fraunhofer diffraction in Double slit also...Can I get a video of that..
+SAISARIKA DEVISETTY
Thank you for watching and commenting. You want a short explanation of double slit diffraction or a detailed explanation as in above video?

Nice😘😍
What course you are studying or preparing?
Should've derived considering n no. Of slits for the general formula
That is diffraction grating. That will also come.
@@SSPhysics I meant n no. Of slits where n is tending to infinity.
Need other chapter videos
What course and university?
Single slit diffraction. Write your doubts here.
SS Physics
Sir i need integration method for the same
So plz help me
yes sir i also need
very detailed explanation.
thank you sir
+Gade Utham
Thanks for comment. Watch other videos also on channel which may help you.
Phaser ?
Phasor method to ad amplitude of waves.
What is alpha here and why we let it
Alpha is phi/2. Where phi is total phase difference.
its helps me
upload on double slit also
Why we let alpha and why alpha/2 only
Just for easiness in calculations. 😊
If you see complete derivation you will understand.
what is alpha?
Alpha is phi/2=half of the total phase difference between all light waves which are diffracted at an angle theta.
SS Physics thank you
Sir samj nhi aaya ..
You have put a hell lot of ads
Sorry but to have free contents no option for these ads.
Book mai do lens liya gaya h
+Sheikh Azhar
In top figure only one lende is shown. First lens is not shown. But it is there, which gives parallel rays which get incident on the slit.

In bottom left figure lenses are not shown just for convenience. But they are there.
