Beats Demo: Tuning Forks

This is a demonstration of the periodic variations in the sound loudness, or "beats," produced by two frequencies that are close to each other, with the beat frequency given by the difference between these frequencies. The nearer the two frequencies, the slower the beats. Thus, musicians "tune out the beats" to tune their instruments to a reference frequency.
It was created at Utah State University by Professor Boyd F. Edwards, assisted by James Coburn (demonstration specialist), David Evans (videography), and Rebecca Whitney (closed captions), with support from Jan Sojka, Physics Department Head, and Robert Wagner, Executive Vice Provost and Dean of Academic and Instructional Services.

Like what it feels like after huffing gasoline ⛽️ 😅
Wahwahwahwah
Brain goes Voomvoomvoomvoom

[@Alexmason83244]

thanks, I studied theories about it but never saw practically... thank you very much.

[@samart3010]

`Wow. wow' What an explanation!..

[@timpaulson9099]

Thanks for making all these demo videos, with my classes out due to corona and no access to my equipment, your videos have helped bring physics to life to my students.

[@dnyanushinde390]

Hi .. where are you from

[@yeahwhatever.]

Yes I'm here after MR sir's wave lecture😂✋ also this demo is superb! Thanks a lot

[@anujtrivedi2606]

Arrrre Bhaiiii Sameeee!!!!

[@Hardikhs2zn]

😛

[@omega6872]

Such a beautiful demonstration. I look forward to more

[@iamhe-man66]

It feels amazing when you experience the theory in practical form thank you so much ❤️🙏

[@AbishkarAK]

thanks a lot for the demonstration. In our school, we are barely shown such demonstrations and i think these demonstrations are absolutely required for learning physics.

[@drbijapur]

Thank you sir..I appreciate your work for making students understand concepts practically.

[@mrittika._sen]

My sir(MR Sir PW) used this vdo to visualize beats frequency... Thanks❤

[@amritagarain1272]

YES

[@wajidulislam3972]

Kab kiya??

[@wajidulislam3972]

He used an app

[@soumikganguli]

Sahi kaha bhai waves lec 9 yakeen

[@IIT-JEE-xv2jm]

my physics teacher ( Ankit bala sir) also used this at unacademy to teach it

[@deepmehta6040]

Fantastic demonstration !!! loved the explanation as well....

[@dita5523]

Nice explanation..I finally understood beat is actually the waau-waau sound...and your necktie is the pattern of piano keys. Wow!

[@pratyushsingh8888]

beautiful demo fs
(love your tie prof)

[@RaviKumar-ov5nl]

Do you hear the wa wa wa?
Me: yes of course, you're doing it.😂

[@gitanshkaushik]

Accurate explanation.
Thanks!

[@fakhrizalarsi]

wow wow wow wow... wow wow. It's super easy to understand, barely an inconvenience!

[@luchomolinari]

I love this... wonderful documentation ❤

[@snehlatajaiswal7366]

Very impressive demonstration

[@shoniziawazir1845]

Absolutely confusion crusher sir.Teacher is the outstanding welwisher and nation builder and worthier of thanks

[@iknowsomestuff7131]

I have never see a tuning fork so I Needed this to understand my textbook . This was nice . Especially the piano tie .

[@UrMomGoes2College]

Haha I thought it was a nice touch!

[@M1551NGN0]

I have my physics exam tomorrow and i didn't understand beats in waves until now. Thank you very much sir!

[@doggee09]

Really loved it great demo 💝💫

[@peterdaughter]

I loved his piano 🎹 keys tie!

[@bingyang1091]

Love the piano tie.

[@AlexHop1]

Thanks, great demonstration! I understand beats in tuning now.

[@mohamedrabie4663]

love how he matches his tie with the topic

[@mahalaxmiv218]

The phenomenon of beating is shown greatly

[@MohanYadav]

I'm a mechanical engineer and I've heard this many times being in India. When temple bells ring, I've noticed this a lot and have wondered what was that wahwahwahwah sound !
And here I get an answer, just amazing. No f**king teacher (not being disrespectful but just an emotional thing), all my life taught me behaviour of Beats phenomenon in real life.
I bow to you!

[@terryivinho3228]

Amazing phenomenon.

[@Hiyori___]

very clear demonstration, thanks

[@LokeshAhlawat-nn1bv]

Nicely demostrated

[@jonnda]

Thanks, I sent this to a non-musician who has just joined the church choir club and wants to know how to tell when something or someone is in tune.

[@babakkarami663]

Amazing demonstration, great job.

[@anowerhossain3705]

Hey, I am from physicswallah ,after lecture of beat formation to see demo of it.
And I got perfect explanation and demo ,
Thanks

Same, i am also from physics wallah.

[@whitewittock]

Is it a bit how noise cancelling works if I understand correctly? The soft part of the 'wah' happens when the wave of one fork collides with the wave of the other fork and cancels it out

[@pramilanmit1876]

Fantastic!

[@rishabhranjan5162]

Does a vibrating tuning fork weigh any different to when it is not vibrating?

[@BadAss_691]

You should also tell about group and phase velocity dera Prof during this experiment.
