@@workharderforurdreams I totally depended on TH-cam for studying and revising .. check this channel “ physics with mo Ali “ … I watched the vids and wrote notes… I actually watched the vids more than one during the exam session .. and then lots and lots of past papers
my mock is unfortunately tomorrow morning and this block is included in my exam so I've been watching your old waves chapter and I can't describe how much it helped and made everything easier, thank you so much !
Hi sir, I really want to thank you for all your videos on summarizing the Cambridge IGCSE Physics chapter. Thanks to you, I was really able to understand all the different concepts I struggled with. I used to hate Physics just because of how difficult it is but you and my current physics teacher have helped to understand and love physics. I am an extended student, and I had no idea about the addition of digital and analogue waves to the Waves chapter. Thank you for shedding some light on this subject.
Thank you so much for this video, you have no idea how much it helped. I have one question though, are we supposed to memorize the wavelegth and frequency for every type of electromagnetic radiation, or just memorize their order?
my physics mock is at 7 am and its currently 2 am, you're life saving, ive literally been using your account since last year because i didn't understand physics at all
Yooo let's go I've been struggling badly with waves, not the theoretical part where we have to just memorise and understand stuff, but the drawing part, I'm struggling with how to place the protractors on the normals, so can you represent these protractors as semi circles on the normals with different coloured lines?
i may be a little late but i found this mnemonic on google to memorise the elecrtromagnetic spectrum... Raging Martians Invaded Venus Using X-ray Guns... hope this helps 20:42
I have a trick to remember all the electro magnetic spectrum waves in order Raw-radio waves Meat-Micro waves Is-infrared Very-visible light Unsanitary-ultraviolet eXcept- X-rays Giraffe-gamma rays Hope this helps❤
my school hasnt updated its book since 2020 and now instead of focusing on this stuff were doing garbage thats been removed which is coming in exams and yet they say we prepare you for externals
Hey Ali, quick question, is the formula always sin(air)/sin(medium) or can it be sin(medium)/sin(air) if its going in that direction?? Please let me know
Basically, a normal is a line perpendicular, or starts at the point in which the incident ray HITS the area, in the phenomenon of refraction. Then, the ray changes its speed since its going towards a denser medium, and the change in speed also results in change in direction. Since its goes into a denser medium, it goes towards the normal; and when the ray fully aligns itself with the normal, a 'normal incidence' phenomenon occurs, which we havent read yet lol. SO, when its out of the medium, it goes back to its default state. And so since it is in its default state, it does not need to go on the way to the normal; and that results in going against / away from the normal and back to its pace. Hope this makes sense! :)
16:12 - Calculating the speed of a wave 28:01 - Applications of electromagnetic waves in communication 29:19 - Analog vs Digital signal types 58:09 - Calculating the refractive index 1:05:32 - Calculating the total internal reflection
its 3am, my exam is day after and im trying to learn the entire syllabus by today. Wish me luck.
Same bhai
Thanks for the curve
@@Away9 will the curve for this year be high or low?
@@Away9 The paper was extremely easy
@@RiyaGoenka-t7q what came exactly?
GOATED TEACHER!
i start my exams in may istg these videos are life savers
Sameee
It would be greatly appreciated, sir, if you uploaded lectures for A levels too! (You literally helped me ace O levels). Thanks alot!
yes, Sir please upload A levels lectures to
Just a random question will these videos be OK for o levels as it says igcse so I was a bit confused
@@subhanahmed4778 O levels and IGCSE is almost entirely the same thing. I had given O levels too using these for revision before past papers.

ill share mine too if i remember XD

Thankyou soo muchh!
cool
Same
YOU ARE A LIFESAVER!!!! when will u upload unit 1 and 2?
he uploaded them!
Thank you, I appreciate all the knowledge you share with us, it helps me really much since physics igcse examination is just in a week😊
Just did my ppr yesterday and I was able to answer the qns all thanks to u,thank uuuuuuu!!!!!!!!
Sirrr you've helped alot 🙏 im glad you're back. Thanks alot for everything man
10:19 is a question that came in our exam and I'm very lucky for watching this vid cuz it saved me

Why am I learning so much new stuff 12 hours before the exam?? 😭
We are together bruv good luck
Us bro us
mr. yu supremacy fr fr
I wish you could teach me maths in a levels. It is such a relaxed environment when studying with you physics doesnt even seem boring or dry
i love these videos so much, you explain so well
i wish id discovered these earlier
Thank you so much for this video, you have no idea how much it helped. I have one question though, are we supposed to memorize the wavelegth and frequency for every type of electromagnetic radiation, or just memorize their order?
pretty sure you only memorize their order 🙏
1:25:17 I don’t think drawing this lens is in syllabus 2024 , correct me if I’m wrong
It is there

Sir thanks a ton for helping me with my revision.
Best teacher in the world
Really he is best teacher
thank you so much for making these videos, I genuinely have no idea how I would've passed without this. THANK YOU AGAIN!! :)
it is a very genius approach to tach with camera on, it just give character to the teacher and make learning so much fun
bro u just saved me and my friend's marks thank u so much😁
Hey could you please do topical questions for igcse physics
S waves and P waves literally came out. What a legend.
the most goated youtuber to me bro is the reason im gonna pass my exam
good luck!

keep up the great work! 😀
do these revision vids apply for may june 2024 too? as in are they the same exact syllabus
Yooo let's go I've been struggling badly with waves, not the theoretical part where we have to just memorise and understand stuff, but the drawing part, I'm struggling with how to place the protractors on the normals, so can you represent these protractors as semi circles on the normals with different coloured lines?
Im just thankful im completing the syllabus in March
Sir can you answer more past papers please
best explanation!!
OH MY GOD THANKS SO MUVH FOR THIS LECTURE
THIS HELPED ME SOOO MUCH 🙌🏻🙌🏻❤MAN U MADE PHYSICS FUN FOR ME SO MUCH GRATEFUL TO U FOR UT EFFORT N TIME ❤❤
Love these videos the content is actually making sense
you are better than any physics teacher that has ever taught me LOVE YOUR VIDEOSSSS

45:09 Should the distance between wavefronts after passing the gap be the same as before? ( in the drawing )
almost the same you can use a divider to measure a similar but wider distance

What software did you use to create those drawings?
POWERPOINT LOL
Sir thank you so much for this, it has geniunely helped me so much whilst revising and in past paper practice.
FINALLY MR YU IS BACKKK
Assalamualaikum, can you explain rules how to make images in case of reflection or refraction
Thank you sooo much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Can extended students also learn from this
U ARE LEGIT THE GREATEST TEACHERNEVERRRR ❤❤❤❤
Thank you so much
U taught me the whole sylabbus in 2 days than my tr who taught me for 2 yrs😂😂
start making videos for AS-level physics as well, please!
can you do also the other two unites
🤍
This might seem crazy but I have my p4 tomorrow extended........pray for me and for everyone
damn same bro, good luck
What did u get bro
Thank you sir i like physics

Sir
Do you teach any tuition I am looking for my child
I still don’t understand about the rays bending towards and away from the normal
Basically, a normal is a line perpendicular, or starts at the point in which the incident ray HITS the area, in the phenomenon of refraction. Then, the ray changes its speed since its going towards a denser medium, and the change in speed also results in change in direction.
Since its goes into a denser medium, it goes towards the normal; and when the ray fully aligns itself with the normal, a 'normal incidence' phenomenon occurs, which we havent read yet lol. SO, when its out of the medium, it goes back to its default state.
And so since it is in its default state, it does not need to go on the way to the normal; and that results in going against / away from the normal and back to its pace.
