My physics teacher actually just sent me a link to your video. To be honest, I'm happy she did, because you explained a lot better and easier than she did. Thank you so much!

Great teaching man, very nice and clear explanation. So much better than my physics teacher! Thanks a lot

Fantastic video, I learned more in 10 minutes versus the 50 minutes it took my professor to explain the experiment. Thank you!

[christinejestel]

Thank you so much! First time teaching the content as a Chemistry teacher turned AP physics teacher This was very helpful!

[KingPapaNoodle]

Thanks so much! Was trying to work through this lab tomorrow I need to teach the students and this helped me wrap my head around what I need to convey to them for the lesson

[jameyclarke]

Thanks David, l am doing a similar lab in class right now and have 2 online lab groups that I am sending to your video. Very nice work. BTW, I actually emailed walter fendt to get him to publish english translation of this simulation. Saw a talk a few years ago at AAPT about how many folks adopt misconceptions about what graphs of sound waves actually represent and I think the Fendt simulation is the best one for showing the correct explanation.

Learned more with you than in 2 lectures of my professor. Great video!

[freddymansour]

Really clear. It's EXACTLY what I'm required to do tomorrow. Thanks a lot.

[yourally]

Really well-structured video. Thanks from a Grade 11 IB kid!

You are a wonderful teacher who is patient

[Valkie]

Omg, you're the best. My physics teacher did not explain this to me at all and you saved my life. Thank you so

[katerinahasiotis]

thank you I couldnt find anyone else that helped me with finding velocity

[haniehseilsepour]

I wish you were my physics instructor, thank you so much for the helpful amazing video sir :)

[vintagesparkles]

for n=1, n=3 for 512 hz what is the length??? is it the same for n=1 and n=3? Please help thank you

[onesmusmukethi]

Educative...I watched this & realized the whole concept.

[matthewperkins]

David, I do this experiment with my Physics class every semester. Our numbers always come up a little lower than the expected speed of sound in room temperature air. i wonder why that is... I love the lab!

[imazariah]

actually u r a good lecture ..this is really helping

[robertowisconetti]

thank you sir. you are a bloody legend

[freshnewday]

Thank you for a great video of clear explanation! This was very helpful.

[pierreretief]

Would like to see some of the experimental values
