Single Slit Diffraction | Physics with Professor Matt Anderson | M28-16

When light shines through a very small slit, it spreads out. But it also interferes with itself and creates a particular pattern on a distant screen. This pattern is called a single-slit diffraction pattern, and it specifically depends on the wavelength of the light and the size of the slit. Let's explore.

He makes writing backwards seem effortless

Nah. He cheats: kzbin.info/www/bejne/eYirfqeJg7Crj6M Cheers, Dr. A

What made sense to me when I thought about what would happen as the slit got smaller was to consider the case where the slit got larger. As the slit gets bigger and bigger, the output wave looks more and more like the input planar wave. I guess in the extreme case, the input and output are the same as the slit in infinitely large

[@yoprofmatt]

Yep, great point. Cheers, Dr. A

[@abul1]

Glad to see you’re back at it again

[@yoprofmatt]

Thanks. Cheers, Dr. A

I have a question, if in the single slit experiment the superposition is lost or in another way the light or electrons are measured or observed, does it produce changes in the diffraction panther?

The counterintuitive problems are always fun!

[@yoprofmatt]

Agreed. Cheers, Dr. A

Sir are these lectures diffrent from your paid course on website

[@yoprofmatt]

The lectures are the same, but the paid site has interactive problems, quizzes, and (obviously) no ads. Cheers, Dr. A

why didnt i find this channel before lol

[@yoprofmatt]

I was hiding. Cheers, Dr. A

Love from india 🇮🇳🇮🇳🇮🇳🇮🇳 sir 🙏

[@yoprofmatt]

Hello to another Fanderson™ in India! Great to hear from you and sending much love back your way. Cheers, Dr. A

[@Qwerty-ls4ik]

great

[@yoprofmatt]

Good to hear. Cheers, Dr. A

You do realize we should not be getting an interference pattern with a single slit, right? It's an ad hoc mathematical contraption.
