Resolution - Rayleigh criterion [IB Physics HL]

[@anirudhtiwari9612]

Iv been religiously watching your videos for physics and math and this is by far the funniest one

[@siriusrevision]

I'm so glad to be able to entertain you :) Cheers, Mitch

[@stefanateljevic6354]

The ending had me laughing lmaooo

[@siriusrevision]

So glad you like it! Cheers, Mitch

[@matheusbellizia987]

Great vid. helped me a lot. Loved the fun example

[@siriusrevision]

Glad it helped!

[@ishanmishra128]

coolest teacher ever

[@siriusrevision]

Thanks - I'm honoured! Cheers, Mitch

[@sixianli1011]

i will take test of light in 30mins, not knowing what rayleigh criterion is. thanks to this video, it helps me a loooooot!

[@siriusrevision]

Hopefully the test went well!

[@Booooscared]

Thanks Mr. Campbell

[@siriusrevision]

You're welcome! :)

[@AlexRapala]

bro I love you so much

[@siriusrevision]

Thank you for the kind words!

Middle finger 10:20 🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@siriusrevision]

hah! Cheers, Mitch

[@agworld7539]

@@siriusrevision thank you do much for these wonderful videos and efforts

Hah

[@cbaa7462]

Thank you!

[@siriusrevision]

You're welcome! Cheers, Mitch

What are the name of the app that you are using

[@siriusrevision]

To record the videos, I use Camtasia to record what I'm doing on the screen. I'm using a writing program called Baiboard, but there are lots of other ones as well that are great.

youre a literal god, you have no idea.

[@siriusrevision]

I'm so glad you like the videos! Cheers, Mitch

[@narunsingh7563]

Hey Mitch, for the example you gave, I think you might have done a calculation error. I got the value of theta as being 2.54*10^-6. Please could you confirm if I got the right answer, or if I am doing something wrong here? Thanks in advance

[@siriusrevision]

I just did the calculation again to double check. 1.22 X 550 * 10^-9 / 2.4 = 2.79 x 10 ^-7. I'm not sure what your error was - try doing the calculation again just to be sure.

[@filippofonseca]

I'm averaging ~7 in my first few months of IB Physics thanks to this guy.

[@siriusrevision]

Way to go! Although I'm sure it's because you're studying hard and doing it yourself. You deserve a high five! Cheers, Mitch

[@DreamtOfSleep]

is there a chance that for each topic, you'll run through definitions and stuff and common questions we might encounter for each topic? love your videos, you are a godsend x

[@siriusrevision]

Well, that's kind of the purpose of the videos themselves. Each video comes from my own opinion on each of the most important subtopics from every topic. As for common questions, those you can practice with past exams. If your school gets you access to the ManageBac Passport, OSC Study has a bunch of past exams where we have video solutions walking you through every step of the way! :) Cheers, Mitch

167.74m

[@leonardopanella4325]

9:17 r should be 250,000 x 10^-3

[@siriusrevision]

The altitude is 250 km, so should indeed be 250,000 m since 1 km = 1000 m.

[@ossabellator13]

You would need a satellite with the diameter of 167.75m to see upto 1mm.

[@siriusrevision]

Nice work! That's a pretty crazy satellite. Good news though, if you change the wavelength of the light, it can make a difference for your resolution as well.

[@boiledoden7252]

Rayleigh like from one piece lol

[@siriusrevision]

Hah!
