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
Is there anyone watching this having a physics exams soon
Tomorrow 😢😅
@@yourgurl_bule languages?
Next week😂
😂😂😂
my physics exam is tmrw
2024.....😢👇
Fantastic lesson I completely understood everything thank you so much 🎉🎉
14:37 It's interesting how math, algebra and graphing is needed in Physics here.
Thank you man
thanks it was very helpful
Thank you
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
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.
Mr K please can you do more exercises on waves
what is the answer for the wave calculation in the video @ 18:31
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

You are so helpful
Hey Kevin, just wondering at 8:53 would A and E be in phase aswell?
Yes
Excuse me but why aren't you using f=1/T and T=1/F as per the exam guidelines?
That was very helpful ❤😅😊
10:56 Does it matter in what way you write it? In cursive or normal?
One more Question missing.
How far will a wave with a speed of 2m.s*-1 move in 3 seconds.
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?
YO
isn't period=1/frequency
Yeah im confused now
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
you are godsent
that middle line is called the equilibrium position 😉😉
Goat
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.😪
Up and down
12:55 My teacher want's us to learn the formulas by the latin symbols. But it's the same thing I guess...
I don't care at all
Then get tf out of here
Soo??🥱
