These are so great for reviewing content on the go so I can listen and still actively review; but I think the perceived frequency and actual frequency are switched in the Doppler equation, I could be wrong though 😁
hi I just wanted to ask when you will be able to finish the content videos for the other books! Will it be by May or June ish? Ofc if it takes longer that is totally fine. I'm using your videos as my content review and it has helped me sm because I'm not much of a book reader, I'm more of a visual learner! I've watched all your gen chem videos and am planning on finishing physics soon hehe
Quick question! When you were talking about the doubling of the intensity you said that it just equals +6dB. Is this always this case or you can just double the dB in the problem and add it to to the original dB? So in your video 90dB would be your answer. Thanks for the videos! They provide such a good layout for studying!
@@VanDoesChemistry ohhh I get it! So you always just add 3dB whenever the intensity is doubled which is 30 after multiiplying by the 10. Thank you so much and thank you for the response! I plan on taking the exam on the 26th, so I am strengthening my weak spots (physics and cars) currently.
Hi! first off thank you so much for these vids! quick question, why would you multiply amplitude x power to get the intensity? (referring to 20:22 when you increase the amplitude and power)
hi! both of these things are related to power through separate equations (the ones written at 20:22) and they multiply because if you think about it like "okay the amplitude changes intensity by 4x once, and the power also doubles the intensity, then overall it'll change by 8x because you double and quadruple it."
why would u multiply 2^2 by 2 (for power). since I is already proportional to A^2, so I understand 2^2 if you double Amplitude. but I = P/A is another equation its Power/Area. i don't understand why you would multiply 2^2 by 2 again. I know it says u doubled power too but I'm lost. Thank you
hey vanessa, so im almost done with content review just got like 3 physics chapters left. So, after i finish with content should i do the milesdown deck like all of it and then start doing uWorld. i believe u said in ur mcat video that milesdown anki was a tremendous tool ? Or what do you think of my plan?
@@VanDoesChemistry so did you do both anki. Miles down and uworld simultaneously? I’m thinking bout doin like a 100 uworld questions a day and then the rest of the day grind milesdowns deck ? U think if I finish like the entire deck and all of uworld bank I can see a good increase in score ?
@@VanDoesChemistry Oh wow thats amazing Van! So, im testing end of march 26th to be exact. Do you think I have time lets say do all of UWorld/anki deck miles and all of the AAmc section banks/q packs and then finally do like 10-11 practice exams 6 NS and 5 from the official aamc? Does this sound feasible and like a good plan to get me like 510+? oh and van I'm thinking as I do uworld and like whatever i get wrong i make an anki card for it and label that deck "missed uworld questions" ? Sorry for long txt btw
@@VanDoesChemistry okay sounds good van I will stick to this plan then! One last question, so do you recommend i do the practice test last (6 NS and 5 AAMc) after i am done with all of Uworld and aamc packs or how did you fit them into ur plan!
@@VanDoesChemistry Yes definetly i agree 100%. So you think if i can finish lets say all uworld and aamc material by end of January or mid February. Do you think the time after that I should just go all out practice test till march test date lets say like 2 a week where I test one day and review 2 days. Then test again and review again? Or do you recommend to do the practice test during the time I'm doing aamc q pack/banks and world? Basically what I'm tryna say is does it matter when you do practice test as long as you get them done and understand ur mistakes right?
@@VanDoesChemistry thank you so much van! this sounds better to save it for last then. So for rn I just gotta go crazy on world and do NS exams once i feel I'm doing pretty good percent wise on the uworld topics. you think its possible to finish uworld in 2 weeks ?
hi! there is no specific equation for it, but you can demonstrate this property by plugging any 2 numbers for intensity into the regular equation and solving for the db value!
I understand that you may want monetize on your videos and appreciate you taking the time to make these videos. But just wanted to let you know that having an ad every 5 minutes is very distracting and quite annoying. It made it difficult to get through the entire video.
Bruh just press skip ads that's what I do. It shouldn't distract you that much. she takes time making these videos and it's gaining popularity so these ads will come up, it's called TH-cam.
@@VanDoesChemistry That person is ungrateful. The fact that you took the time to do this enough. It really isn't hard to press skip ad. You're helping us a ton. Get your coin sis!!!

Laughed for the first time today at the "turtle" car! You are making my MCAT studying bearable XD
Two years later and your videos are still making a change, thank you.
🐢 has my whole heart
🥺 you have mine
im studying for my mcat in september at the moment, and these videos help so much! ty for your time and the work you put into these videos
how did your exam in September go?
@@bryanchen4342 hiiii it went really well :)) all done now
lets say we have a car.. lets say we have a turtle - cracked me up! :D
Thank you! I've really been struggling to get through the physics book and your videos have been a life saver
won't decibels increase by 3 when you double the intensity? Because 10log(2)= 3 ?
Thank you so much! I was crying in the bathroom for 3 hours before watching this vid. Made my day :)
This is so nice since I missed almost every sound/wave related question on my last practice test smh. Thank you!
you're too good at explaining, thank youuu tons
These are so great for reviewing content on the go so I can listen and still actively review; but I think the perceived frequency and actual frequency are switched in the Doppler equation, I could be wrong though 😁
another way to think about longitudinal waves is a speaker cone or a spring (with an attached mass at one end and fixed at other end)
bro that is a fast turtle
These vids are gold, glad I found them before my exam
using this videos instead of reading kaplan books, let's see how it goes... i'll keep you updated for those future test takers.
You are an an excellent lecturer!
This turtle got the mutations they always talk about in the biology section of the exam - he's zipping
I feel like i robbed you by watching this for free. You're the best!

just wanted to add no rush! I understand you're premed as well !
you're a life saver!! thanks a ton for your help - you've carried me through physics :)
yo GTFO this WAYYYYYYYYY better than what those kaplan books teach. you should have wayyyyyy more subscribers! you got my vote
CAR? X
TURTLE? YES

I'm so sorry, the correct change in dB when intensity is doubled is +3dB. You take the original dB and add 3 to it, do not double the decibels.

Hi :) I’m just wondering, when will this physics series be finish? :) Thank you so much btw for doing this :) you are a life saver!!
Are you going to cover all the Kaplan books? This is so helpful, and free!
YOU'RE MY FAV TH-camR! lol
omg I think I am in love with you

Is there anyway to complete the whole MCAT sections ?
definitely liking and subbing

can someone explain the mnemonic Dom/sub. I think I get it but im not sure
11:08 does she mean speed of sound instead of frequency of sound?
Could you do lens/mirror video pleaseee?
@@VanDoesChemistry omg i love you
You're too OP
this is so helpful! Can you do this for all the Kaplan MCAT Books!! Thank you!
@@VanDoesChemistry You're very helpful. God bless you and we really appreciate this. Really.
I can’t wait till you cover lenses. My test is this month and I’m lost 😞
how'd your test go?
@@dom6783 I’m retaking it 😔 this test really is challenging! I did good on the aamc material but on the test it felt different
@@JulioCarRosales did you end up passing?
Hi Van! at 23:50 s in this video, how we find that by doubling the intensity db will increase by +6? do you have the equation for it? thanks a lot
hi! there is no specific equation for it, but you can demonstrate this property by plugging any 2 numbers for intensity into the regular equation and solving for the db value!
@@VanDoesChemistry Thank you for your help.
@@VanDoesChemistry I keep getting three
oh wait it is 3 db!!
I added a correction in the description, thank you for pointing this out!
these are late uploads 👀 #teamnosleep

Longitudinal wave= slinky
off van won't forget Dom/sub
Can you please do chapter 11 please pretty please
