Single slit interference | Light waves | Physics | Khan Academy

What happens when there's only one hole? Created by David SantoPietro.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

As representative of the state general of the Dutch royal democracy I hereby pardon your mispronunciation.

[Sofia-owgo]

You made single-slit and double-slit diffraction easy to understand and now I am not panicking over physics anymore, you're the true og, my good sir.

[milkwasabadcholce]

THANK YOU, why isn't Huygen's principle taught BEFORE two slit interference in all the texts, you'd think this knowing this beforehand would save you from a lot of misguided connections.

[adolphmatjukotja]

This concerpt never made sense to me until I watched this video, , , thank you a lot for the lesson

[ahmedibrahim]

i like how he didn't ask for a like and sub in the end and simply said "you're all good"

[agumonkey]

if huygen's interpretation was taught to me before geometrical optics I'd be an astronomer/photonicist. It's such a leap from too simple -> crazy, to weird -> everything become simple

[unorthodox]

😭😭I wanna cry coz I still don’t understand this

[leonordin]

Its so stupid my testbook tells me nothing like this and expects me to understand. As others has mentioned you are a hero. its so easy to enjoyable to learn with your videos. thumbs up

[MS-qhiz]

The ONLY single slit diffraction video that’s actually makes sense. Thank so so so much Khan Academy!! Saved my A level!!

[varunmudgal]

one of the best explanations of single-slit diffraction. good job

[danvladoiu]

Your videos are absolutely brilliant! Excellent job and thank you for making this topic so clear and visual!

[fenrir]

Twhen my school teacher taught me this, i was unable to understand it, but with your explanation i think i understood it just fine.
THANK YOU,

[namename]

I have never had such a strong sense that something is wrong

[DanStep-yopv]

Finally! Thank you for your amazing explanation. Absolute legend.

[reetichauhan]

Can someone please just make a playlist of all videos by David SantoPietro. That would just make life so much more easier.

[Dhruv-Kumar]

I had to watch this 3 times to finally get it

[rifathasan]

You made this critical topic easy to me. Thank you so much sir. Lives in Bangladesh 🇧🇩

[alexandramitric]

omg, what a good way to explain it visually, exactly like how i like to learn physics. THANK YOU

[Fransamsterdam]

Very interesting, especially for a lay man who has been told so many times that only a double slit will show interference, thanks to quantum mechanics...
By the way, your pronunciation of Huygens is quite good if I compare it how 't Hooft is sometimes announced on YouTube. :-)

[jinghuiyu]

I don't know if i have got it right but, the way you cal the different wave lengh as w/2*sinΘ confuses me, because the right part of light from the footprint seem to have different wave distance
