Go watch mechanical energy videos and then decide if you'll cope or not😭. If you gonna choose physics be ready to study HARD! Without hard work you'll fail the subject
Frequency is the number of waves that pass a fixed point per second the 1 will change depending on the number of waves (1 represents the no of waves ) so if there were 2 waves that pass in one second it would be 2/T ( the T represents the time it takes for one complete wavelength to pass a given point measured in seconds)
You just saved me from getting kicked out of my physics class
14:37 It's interesting how math, algebra and graphing is needed in Physics here.
Mr K please can you do more exercises on waves
Fantastic lesson I completely understood everything thank you so much 🎉🎉
Is there anyone watching this having a physics exams soon
Tomorrow 😢😅
@@yourgurl_bule languages?
Next week😂
😂😂😂
my physics exam is tmrw
2024.....😢👇
Best Physics teacher out here. 24:08
is anyone watching this to see weather you can Cope with physics next year😅😅
na mate but that's very smart of u,u will probably cope😂
I'm writing tomorrow and this is the last topic I need to practice and read
Be prepared.😪

I wish I would've before I took this subject
Thank you man
Thank you
what is the answer for the wave calculation in the video @ 18:31
i really enjoyed the calculations part
how do you know which equation to use if your calculating waves?
do you use F=wave or T=seconds ?
seconds wave
Depends on which one they gave u in the question or the easiest one for you can still get the same answer
10:56 Does it matter in what way you write it? In cursive or normal?
Sir can i ask?
Will it be wrong if i used th formula
V=d/t
to find the speed of the wave.
According to my understanding, V=d/t applies to situations we're we know the distance, if not we use the other one.
18:28 what's the answer to this question?
Is it 2.5m.s‐¹?
Legend says he never responded
@@Ibreaksouls
I literally already got my marks back, and I'm still waiting 😫🫣
@@saf1078 I don't think he will respond anytime soon :'(
But your answer is indeed correct @saf1078
@@saf1078did you get your marks yet?
That was very helpful ❤😅😊
Excuse me but why aren't you using f=1/T and T=1/F as per the exam guidelines?
You are so helpful
Thank you so much
thanks it was very helpful
When you were speaking doing examples of in phase, was A not in phase with E,I and M?
Wait so does the 1 in f=1/T change depending on how many cycles there are?
No it's constant because frequency is the number of waves that move past a fixed point per 1 second
Frequency is the number of waves that pass a fixed point per second the 1 will change depending on the number of waves (1 represents the no of waves ) so if there were 2 waves that pass in one second it would be 2/T ( the T represents the time it takes for one complete wavelength to pass a given point measured in seconds)
Hello sir, what does 'in phase' mean
I think he means, like particles that are moving the same way ,like in the picture between the two points they both moving up and down
It means that two waves or pulses are in the same rest position or equilibrium
For you to always remember know that in Phase is constructive interference and out of phase is destructive interference
It is when two points of a wave are going in the same direction
phase is another word for state in this case
YO
isn't period=1/frequency
Yeah im confused now
that middle line is called the equilibrium position 😉😉
One more Question missing.
How far will a wave with a speed of 2m.s*-1 move in 3 seconds.
6m

12:55 My teacher want's us to learn the formulas by the latin symbols. But it's the same thing I guess...
Up and down
you are godsent
استغفر الله العظيم رب العرش العظيم
ARE YOU CHRISTIAN?
I don't care at all
Then get tf out of here
Soo??🥱
Fuck you were learning dude
