watch in 1.25 speed then thank me

I literally didn't understand anything about waves and now i learnt and full understood it in 8 MINUTES! Thank you Najam!

wow! finally i understood these topic after 21 years from the day of my birth. so so so much love . thank you sir

he's funny accent make it hard to forget lol. while answering the test at school I would imitate he's narration then giggle for a bit and I got quit a huge score lmao

I passed in my physics test because of the video. Thank you so much:)

I ain't gonna lie. That was quick and easy to understand. I learned what's in a wave in just 8 minutes. Fantastic!

Measure ❎ maiyer ☑️

Thanks sir I have passed my physics exam 80% marks thank you very much sir😍😍😍😍

remember: amplitude is never -ve its always +ve displacement can be -ve but amplitude will be +ve always

Nice I am a physics professor You are conveying the subject very perfectly 🎉🎉

Beautifully explained. My concepts are crystal clear now 😊

I was very confused in this topic And now after watching this video I have no confusion thankyou so much

Thank you very much. At first unable to understand these concepts but now it is clear

You have cleared my all confusions about these topics, thanks a lot

Very helpful Very helpful I Recommend to watch this video one time or more because it is most important and most helpful. Thank you so much I was very confused about these things Thank you ..🙏🙏

Thank you, the illustrations made this really easy to understand

Nicely explained. I understood everything

Thank you sir, Your explanation is next level

it's very clear. Thank you!

this discussion was outstanding.... this chapter in my physics had missed in my class.... but after seeimg , i have cleared my doubts..... Thanks @NAJAM ACADEMY

omg this helped me SO MUCH. i couldn't go to school for 1 week because i was sick so i didn't learn about this stuff and now i have a test soon and i was able to learn all of this is 20 minutes. this was explained SO well. thanks!

Good work! One suggestion if you can also visualise which type of circuits/electronic devices have been built up based on the lectures of your videos. Because at the end we should learn how to implement these concepts electronically.

I think that frequency is the reciprocal form of time and its S.I. unit is "/s (per second)". For example, when we say 3/s, it means that 3 in the first second, another 3 in the second second to make 6, another 3 in the third second to make 9, and so on. I think that frequency is like speed, but without distance, but frequency is equal to speed over distance.

Sir Your teaching methods are very useful

Amazing vedio but the sound is funny kind of scary 😂❤️

This is the most amazing video for this topic!thanks a lot!!

Fully conceptual videos thanks for making this type of videos.

I am just studying this for timepass but you explain it so perfectly absolutely love it keep up the good work👍👍

It is very easy to understand these topics in 8 min .THANK YOU SIR 🔥🔥

Sir upload an video on the bases of pitch and amplitudes difference and if the pitch of every wave is same and loudness is different what is the consequences

Simply but elegantly explained😀😀

Your explanation is too good I understand very clearly. Thanks sir

I am watching every video of you sir. From everytime i am feeling satisfied from your explanation and teaching. And the concepts are crystal clear for me. Thank you sir🥰🥰🥰. Hope you will do so much videos like this in future.

Great job keep it up,,, easiest way to learn from Najam academy

"Once a hero, always a hero" - Albert Einstein, probably

Thank you for the clear information. I understood very well

Thanks sir.... Thank you very much for this video..... God bless you sir

Thnku bhot ache se clear hue hai yeh 4 tems💯 Thank alot

Really Good Video don't care what people say about how you say its different for everyone :)

Thank you sir .Now my basics is completed.❤❤

Loved the video♥️♥️♥️ Keep up the good work 👍👍👍 😊😊😊😊😊😊😊😊😊😊😊

Expressed in an excellent manner

Very very very very very good teaching.... Easy understanding....

Thanks you so much.I understood very well.

Awesome explanation... Thank you so much Sir... Stay blessed 🙏😇

Brilliant Video Sir 👍 Thanks A Lot

Hey man, can I reduce somehow the noise of a vibrating motor in a phone without reducing the vibration?

Thanks a lot for easiest way of explanation...sr

You just solved the entire weird confusion in my mind which was disturbing me since school for more than 5hrs

Wow love your explanation

your videos saved me thank you!!

very good video. Just one submission. The right word is 'Refraction' rather than 'Rarefractin'

Thankyou for teaching so clearly.

First time l learnt this topic. 👌

I really like your video. thank you very much!

Very useful for me thanku sir for this amazing video about frequency, amplitude and time period thanku sir

You explains the concept in ever easiest manner.keep doing sir. Great job👍👍👍

Nice ❤❤ illustrated content, i really appreciate the editor and explainer

Excellent way of teaching I really enjoyed

Well i had understood best .thank u sir .

Thank you so much ❤️

Best video 💕, I was just looking for this

Very good channel for basics term OF PCM

Great class sir, thank you very much!

Hi, I like your lecture. Thanks

Tnq sir . Superb explanation👌

Sir thx for this my exams are tomorrow and this was helpful you accent was not a problem

Appreciate it bruda!! Nice explanation there!!

Woww,after 25years I understood what is frequency

Waaaw

Mind blowing explanation...😁

If frequency increases in SHM, so does the acceleration. But does it make sense that high frequencies impose such a high acceleration? How do you account for this biased acceleration given by high frequencies. For instance, for SHM, a=( 2*pi*f)^2. How do you account for the fact that lower frequencies have more detrimental effects that high frequencies?

Thank You for this video Mr

Thank you so much ☺️

Thank you so much it really helped me 😊

Thank you...that was clear

Teach well. Thank you.

Thank u for basic information.

Amazing video! Help me so much. Thank you

This guy is a absolute g before a test

Thank you for explaining in such a way.. It's so effective👏👏

Thanks Ur the best❤

Thankyou sir this was very helpful 😊❤

Thank you sir I topped my physics test because of your video...❤❤❤❤❤

so educative thanks so much

This is what I've been looking for

Amazing and clear explanation!! 👍👍 Love from India ❤

Thank you so much sir ji.

Thanks for your this amazing smally vdo 😊😊😊😊

Very impressive video . Thank you . 😊👏🏿

Another awesome explanation

I wanted to ask that while explaining wave cycle you said that one crest and one trough forms one oscillation. Can one crest and one trough also be called one vibration?

BEST EXPLANATION!!

Tomorrow is my presentation on properties of sound wave thank you

Thank u so much teacher

Thanks clear concepy really

Thanks a lot sir😊

You tube video is helpful as a friend.

Now I have Gained confidence for this topic

Thank you so much sir ALLAH blessed you 🌺🌺 kindly make video on the topic of periodic waves . Humble request sir.🌺
