Please note, I drew theta 2 incorrectly on the refraction diagram. This is fixed on the pdf. Silly me. Btw, watch the new & improved vvideo: th-cam.com/video/It50NXN0Rrw/w-d-xo.html
Uhh hi, the angle isn't corrected in the PDF, i momentarily forgot everything about waves and couldn't figure out what was wrong. Theta is supposed to be with the normal right?
Wow this is totally fabulous and just miraculously taught me everything about the topic of waves even though I'm a total freak and can't even understand some very basic stuff as I'm a newbie to physics but you're a mega-legend and totally rock! :-)
probably already mentioned - but check the diagram for refraction/snell's (theta 2 should be to the normal) - couldn't DM - sorry for broadcast message but hope this helps other viewers catch this too! (Otherwise video is great - thank you!)
Hello, science shorts. I just want to recommend for you to upload a video explaining the "f=1/2l[tm] formula. If you could explain that, it would sincerely help. Thanks,
Thanks for the videos sir, got my exam tomorrow. Quick question, when you got the order as 3.7 with the d sin theta equation, you rounded it down to 3. When you have a decimal answer do you always round it down?
Good video but is it wrong in a couple of places: 1) electrons are fired at 2 slits, they travel as waves - we know this because they create a diffraction pattern. However when they reach the screen (behind the slits) the electrons behave as particles. After a while a diffraction pattern builds up which is composed of many dots i.e. many individual electrons striking the screen. This is an example of "wave particle duality" because the electrons are behaving like waves sometimes & sometimes they behave like particles. It contradicts your 1st claim that waves transfer energy & not matter? 2) You are swimming in the sea looking for surfable waves. A wave arrives & lifts you upwards. Thus the wave has transferred energy into you moving you upwards. This contradicts your claim that transverse waves oscillate perpendicular to the direction of energy transfer? The main direction of energy transfer is towards the beach. We know this because the wave energy starts out in the sea & then moves to the shore where we hear the sound of waves
You casually just went through the entire topic of waves in five minutes , you are a bloody legend sir
I know, i have been trying to learn for over 3 months but couldn't, you seriously are a legend
this channel is so good - I thought physics was really complicated until I found this

@@reyla79 A year late: Yes, always against the normal.
Hello i am looking on the waves pdf and half of the stuff isnt there might i be on the wrong one?
@@fahrenheit2101This is even later, but I pinned it when I posted it.
woah this is the best physics teacher ever !!! I got 98 out of 100 just by watching this video for my waves test........ Absolute Legend!!!
Thank you so much. This is such a good video, straight to the point and also the whole topic compressed into 5 mins.
People who dislike, just don’t understand how good you are
It was one person, which I suppose was a karen of some sort XD
Ur really a life saver for exams, just sums up everything I need to know for my exams, thanks a lot
Legit hv a test on this next week

The calm in your voice makes this so much better lol thank you so much!
have my exam in 10 minutes thanks mate
Such a helpful video for revision. Thank u. I usually never comment on videos but this has been incredibly helpful for me
this guys acc goated? i missed 3 weeks roughly of school due to being severely ill and wow, he's getting me through my mocks
thank you so much this really helps me for after spring break
what a guy, absolute madlad!
You are amazing I hope you know that
The way im going to fail physics now.😭
Thank you it was really helpful
I think for the destructive path difference it’s meant to be (n+0.5) lamda rather than minus. Otherwise, great vid
All depends whether n starts at 0 or 1. I'll probably agree with you now though.
u deserve subscriptions of all a level students
at 5:19 , the theta 2 angle should be against the normal. No way this guy has less than a million subs, Absolute LegenD!
See pinned comment
Thanks chief, will help me with the test.

Already fixed on pdf.

We need a face reveal of this legend
All over youtube bro.
Kinda creepy?
isn't antinode where construction interference occurs, instead of both?
That would mean the string would never go up and down - it would just stay a constant peak.
You've missed out optic fibres/cladding.
Flip.
Apparently it's in the astrophysics video
so do we need to make a single slit if we use a laser?
No - already coherent 😊
Hey, is there nothing on optics? Thanks
See astro vid.
IS THIS REAL ,I DONT THINK SO ,
EDITING AFTER WATCHING : ITS REAL ,WOW .
Bro chill.
I like how the comment isn't actually edited

1. That's the paradox - electrons act like waves AND particles.
2. Matter is displaced, but not transferred from A to B.
@@ScienceShorts if you fire electrons at a screen & they hit the screen then the electrons move from A to the screen.
