MCAT Physics: The Doppler Effect in 6 Minutes

[@devbatth7415]

Great video! I just want to say that I take my mcat Friday 05/24 and you have helped me a lot on my mcat journey. If I would have found you earlier in the process I would have definitely taken a course from you instead of the other courses. Thank you for your help!

[@bremmethod]

That means so much - thank you! And good luck on your MCAT Friday!! Let me know how it goes

[@ShakyaGray]

Your videos are really helping me in studying for the MCAT! You are great at breaking down concepts to make them easier to understand. Thank you!

[@bremmethod]

I'm so glad that these videos are helping on your MCAT journey!! best of luck!

[@daniw4909]

I just noticed how new this content is!!! You're doing an incredible job simplifying concepts and making things easier to understand. Keep it up and thank you for making all these MCAT prep videos!

[@bremmethod]

Thank you so much! We'll keep the videos coming!

Hi! your channel has been helping me a lot for studying mcat. Thanks for sharing!

[@bremmethod]

So happy to hear it's been helping!

[@Aubrey.Rhodes]

@@bremmethod Hello! do you recommend any study resources for mcat? 😊

[@bremmethod]

I usually suggest students choose resources that best fit their learning style and preferences, but I do love the UWorld QBank (I use it for all my programs), and of course the AAMC Online Resources are great practice!

[@Aubrey.Rhodes]

@@bremmethod Thank you so much for replying. I also use 30 day MCAT resources. If u want free flashcards i could send them to you. They're very useful. I've sent them on IG

[@Aubrey.Rhodes]

@@bremmethod thank you so much. i also recommend resources from 30 Day MCAT. got a 518 as my 1st attempt.

how do you only have 1k subs. youre amazing

[@bremmethod]

Thank you so much!

Thank you! quick question, @ 05:00 you said wavelength is held constant. how can that be, if shift means the change in wavelength or apparent wavelength? thanks

[@bremmethod]

Great question! Doppler effect, we are directly comparing frequencies, not wavelength. If the speed is held constant, wavelength will also change (it has an inverse relationship with frequency, so if frequency goes up, wavelength will go down). BUT if we are also observing a change in wave speed with frequency, then wavelength will stay constant! A good way to think of this is with our equation c = fλ. One of these variables will always need to stay constant in order to compare two other variables. The question set up will let you know which one to hold constant, and which two to compare!
