This was an enjoyable series. I stumbled across it while trying to get visuals on what actual waves inside a wind instrument look like and decided to stay for the other videos. Most diagrams only show you a string-style standing wave oscillating up & down with nodes & anti-nodes but your depiction of the longitudinal oscillations of the spring and the pressure waves inside an air filled tube were quite useful for understanding
Glad to help!
The passion and energy you carry while making the videos is unmatchable. Thanks from India.❤🎉
Hey wassup Mr.P! I’m not even doing this in my physics class, but I just wanted to let u know that I probably wouldn’t pass my AP physics class if it wasn’t for these videos. Thank u!
Thanks for letting me know. Best of luck with the rest of the class!
I stumbled upon this video while researching for the beat concept which is the reason behind the wavering sound of a tremolo harmonica. And what a wonderful demo I got to see explaining beats. Thanks a ton ❤
Another legend addition!!!... Great work 👍
I found this channel very helpful. Visualization are amazing and that's what helps me the most.
Oh my gosh! This was actually life saving. Couldn’t understand it anywhere else.
Love this explanation ❤.
superb demostration, thanks buddy.
wonderful demonstration. Thanks a lot
You are welcome!
This is an excellent demonstration and explanation!
Thank you!
Hey Mr.P Thank you so much for this series!!! These videos finally cleared everything up for me and the practical demos were super helpful!! :)
You're very welcome!
Was studying waves , pricisely saying beat frequency ( f2-f1 and all in physics but wanted to FEEL the formula , your video helped
Thanks mr.P
That is awesome demonstration Thanks sir
Great work sir
Thank you so much! I have no words to give you thanks!
Glad I could help!
Thank you so much🙏
Practical demos helped me a lot in understanding this😊 Thanks!
You are welcome!
Amazing indeed
Thank you so much! Added wisdom to know if my guitar is not in tune when playing🎸
Really awesome 😄
Thank you!!!!Was very informative!
outstanding brother
this was awesome!
Really really .....no words for your work👍and❤️
Extraordinary amazing lecture
Glad you think so!
Thank you gentleman for making me understand the music by guitar.
In Music world world, the frequency is referred as note I suppose
Amazing
Thankyou so much
Hey, I noticed in my years of flying that when the two engines are spinning at nearly but not identical N1/RPM (typically during engine start), they make this “wawawawa” sound, now I know that this phenomenon is called! Thanks!
Awesome! Thanks for sharing. That totally makes sense.
@@FlippingPhysics Naw worries mate! Glad you could help me!
Superb lecture sir 🙏
I am from India.
I loved your work.
After watching this video.
Now I am following your videos .
Thanks a lot 🙏🙏
You are very welcome!
your physics videos are so interesting brooo......really we will love physics
Very nice
Hello I have a question. You demonstrated with two overlapping sine waves. I have a sine wave at one octave and a triangle wave at the octave above playing together at the same phase start position. I have, what I believe is, Beat Frequency occurring. Do you know why? Thanks for your help
Underrated channel
Agreed.
Genius thank u
you deserve million subscriber.
That would be lovely.
Great and interesting
Thats would be a great introduction to furier!!
Could you do a derivation of the beat frequency at some point?
great work!!!!!!!!!!!!!!!!!!!!!!!
Thank you so much 😀
Why is it so easy to understand what you are teaching? I read 2 books about beat frequency, my lecture notes, my professor's notes and still didn't get it... I came to see your video and now I finally got it!! Thank you very much Sir!
I am very glad I was able to help you learn!
Superb bro,big headache for me gone
thanks man you the best
You're welcome!
Couldn't get it until I watched this video and I'm finally ready to go for my exams. 👍Thank you!
I hope the exams went well!
@@FlippingPhysics Yes! It all happened after watching your RUclips videos ❤️YOU'RE DOING GREAT JOB👍
Sound is really cool
Agreed.
what happens when two waves of slightly different frequencies travelling in different directions meet?
graphically, I feel like they will produce beats but mathematically, I'm not able to derive it
Awesome ❤️❤️❤️👍👍👍👍
Many many thanks
My teacher punished me when i asked him what is the beat but thanks to u i have learned it
beautiful physics
I'm glad you think so. I'll pass the word on to Bo.
how are u so gud in explaining ...far better than nptel lectures
Glad you find my videos helpful. I hope you able to learn from me!
Also, do you have this tune uploaded anywhere ? Like SoundCloud or here on youtube
What "tune" are you referring to?
@@FlippingPhysics "fliiiipiiiiiing phyyyyyyyyyyyyyysiiiiiiiiiiiiiiiiics" in the beginning
@@lincolndexter9514 Ah, I forgot that was at the beginning of the video. The answer is, "No, I have not loaded that song anywhere." I guess I probably should at some point.
@@FlippingPhysics thank you for your reply

What app are you using for tone generation?

Thank you! What app was it that let you produce those tones??

@@FlippingPhysics Thank you so much! New subscriber here.
Now i just realized that I've been using beat frequency in tuning a guitar
wow
🙌🙌🙌🙌
😀😀😀😀
I once took a Uber ride with a driver who drove with her window only slightly open, which generated a loud beat frequency effect with the wind coming through the crack in the window. It was very, very annoying. I have no idea how she was able to tolerate it!
Woooowww
If given a beat, how could one determine the two frequencies that make the beat?
If the only information you have is the beat frequency, you cannot determine either of the two frequencies which are creating that beat frequency. Two unknown variables and only one equation.
@@FlippingPhysics I see, would other variables like period be needed to determine f1 and f2?
@@FlippingPhysics Fourier says Hi
Why isnt there complete destructive interference where they are out of phase? Amplitude of both waves is same.
I'm "Bo"wled over!
he he
What's up hun?
get good
If ya don't stop talking for a minute how'd we listen to the beats man... 😒😒😒😤😤
Amazing
