How To Solve Doppler Effect Physics Problems
HTML-код
- Опубликовано: 2 окт 2024
- This physics video tutorial provides a basic introduction into the doppler effect of moving sound waves. it explains how to solve doppler effect problems in physics. Any time the source moves toward the observer or if the observer moves toward the source, the detected frequency will increase - that is - the observed frequency will be greater than the frequency emitted by the source. The source can be an ambulance truck or a police siren. If the source moves away from the observer or if the observer moves away from the source, the detected frequency will decrease. This video contains plenty of examples and practice problems of calculated the frequency detected by the observer.

Hi sir! For the last answer:
Since you are using direction doesn't the sign change.
Doesn't Fo=900(343+25)/(343-20) become Fo = 900(343+25)/(343+20) since you have to take direction into consideration or.....
you taught me more about the doppler effect in 30 mins than my physics teacher did in 200 mins of complete waffle. ive watched quite a few of your vids and youve completely changed my grades. ill never be able to thank you enough.
i was failing dopplers effect until i watched this. this man is a savior
Waffle? My teacher literally pancaked the entire year
Why do I see this topic so ez n basic
I have a physics unit test tmrw and i didnt understand the unit because how bad my teacher is, watching him it took me only a couple hours to cover more than 5 topics in one unit
my professor is so bad at teaching, this is saving me as well. got my final coming up this is the last chapter i have to learn then i pass the class 😄
hey, just wanna say thx for your videos, they have helped me so so much already.
@toasty bread kon
Physics has always been my weakest subject. You're truly an angel for explaining everything so clearly.
I was trying to wrap around my brain on this for the past 3 hours with insignificant progression till I stumbled upon this video. The explanation is logically systemic and the examples are just perfect. That begin said, I actually clearly understood the concept of Doppler effect within 20 mins. Always a life saver JG! Thank you!
LMAO I CAME FOR UR VOICE 🧍♂️
Don't we all 😃
lol.
why is everyone simping for his voice? Where do y'all come from?
🙈👀
You came??
I didn’t even realise how little I knew about this section until I experienced the massive influx of understanding after watching this video
Im 15 and I understood, very simple clear and good explanation
bro, you're amazing, I have an exam on tomorrow and didn't understand when to use the positive or negative sign, thank you so much, keep it up, you're cool!
This one was really helpful 😭 thanks a lot
Great class. Thanks, it helps a lot ❤
This guy is amazing in explaining the aspects and his videos always help me to understand the work
himmmm what an amazing teacher you are!
thank you for your all hardworking to teach.
May Allah bless you. You have been of great help to me and my engineering classes.
you are a life saver
I just want to say thank you so much.😘❤️
Sir, after struggling for 30 mins on Khan Academy, you have saved me with this single video!
Have a test tomorrow am I cooked?😢
Wow, what a teacher!
Without this man I'd be literally failing my course in campus..thanks Soo much bro👊
I wish my lecturer watched this and taught the same way
Thank you so much, your explination was on point... you helped me a lot
Do you like this position?😍💞😩
..😀👋
I-
...
This guy is amazing
y'all all from that video huh? CAUGHT you now say cheese 👁️👁️📸
Cheese -3-✌
^з^✌
I've missed the past 6 lectures and I am getting almost only A;s in each exam thanks to this guy. love you
Y'all really just coming for the voice srly atleast listen to his explanation
hello, thanks so much, this has highly helped me revise for my exams next week.
AMAZING VIDEO REALLY HELPFUL LOTS OF LOVE
Thanks 🙏,it was really helpful
NOT EVERYONE COMING HERE FOR THIS MANS VOICE
Very nice, now I am able to solve any problem of Doppler effect, thank you very much
Hey sirrrr i love this position
Gurl-
PLS
PLS LMAOSKAOA
Bro? 📸🤨
I tried calculating the relative velocity of the observer and source and tried to make the fraction simple but my answer differs a bit... But they are close
Thank you so much sir❤
Example: Truck with four 15 inch subwoofer's is passing you from left to right.
The closer he gets to you the louder the BLOOM.
I experienced this today.
👊😎
Finally I understand ❤️
thanks mate 🎉
This video has helped me so much,I am writing finals soon, and this was incredibly helpful, thanks so much
why does this different ad keeps coming , when I'm finally concentrating to study through your video .
So whole Simple Explanation is awesome. Thank you very much
Thank you so much for teaching the doppler effect! You explained it very well and those practices made it 10x better.
Thank you so much...you deserve an Oscar award for the best online tutor
Omg thank u so much I never thought I was gonna understand this lesson I was literally hopless I remember in the term exam I just memorized the all 6 formulas without understanding how to use and it showed up in the exam and even though I had all the 6 formula in hand I couldn't use bc I didn't have an idea if it I just kept trying by replacing the v's values around and the time went off and they took the paper exam🙂 but now I understand it thank u soo much again u literally saved me 😫
Think you vary much
Thank you Sir
My answer for that number 4(b) is 2674Hz, am I correct please?
Man this is so cool, I got "A" in physics because of you. You're the best
omg THANK YOU
Yernn Naol first 😫
If you approach or exceed the speed of sound would this still hold true
This was really helpful
Thank you
SHEESh explaining the denominator and numerator importance cleared it all up, thank you
the last problem has 2 solutions since the drivers could be moving in opposite directions
Doppler effect explain expansion of universe....
It is mentioned in quran 1400 years ago :-
{And the heaven We constructed with strength, and indeed, We are [its] expander.}
Alquran -(51:47)
Y'ALL WILDIN 😀😀😀😀😀😀😀
caught in 4k 😟📸
I will end up owing this guy my whole damn medical degree one day
Can you consider the ambulance question but if the ambulance is parked and the observer travels toward the ambulance at the same speed, 30 m/s. Logically, I feel as though the answer should be the same, however, when worked out, the original f' is ~877Hz and in my question it is ~870Hz. Can you explain why there is a difference in observed frequency between these scenarios? Thank you.
🌸💙🌸💙🌸💙🌸💙... i needed this info for tomorrow's final exam.. my teacher was taking so long to answer my questions 👍
I had to pause the video at 15:47 to say thanks for your tips sir its alot more easier and this is from some one who never did physics at the start🙏🏼🙏🏼
I may not know math very well✋😪
But i can bark😏
BARK BARK WOOF GRRRR ARF!
Thank you for this video. Very informative
thank you so much sir by the merit of teaching with such skillfully may you attain the supreame bliss of nibbana love from sri lanka
have an exam in two hours RIP me
I the third example are they not moving away from each other giving us +vs and -vo??
Me, when I realize I can't just use the relative speeds of the objects 😳
😅
Why in problem 3 the speed of the source is negative ?! I mean it gets closer to the observer!!
I just cannot explain how much this beautiful person has helped me. Live long people like these !
I have seen this video before why you upload again ?
For learning purpose
So he can make people pay for the original video.
Thank you so much I was confused about the Doppler effect and after 20 mins I can now understand such a great video
I am studying dentistry
I just come here to increase my knowledge
Thank you.
when ever i Search edu video videos will comes up of ghis guy.
I have my finals in a few months and you’ve just saved me.
Asante
A car moving at 20m/s with its horn blowing at a frequency of 1200Hz is chasing another car going at 15m/s .what is the apparent frequency of the horn heard by the driver being chased ? Take the speed of sound to be 340m/s
Any one to attempt please
I appreciate you making studying easy and simple.
Wait?
I thought VS=+ if the Source if Moving towards the Observer
Why is the VS=- if the source is moving towards the Observer???
You're right if you kept the positive sign beside v observer and negative sign beside v source constant you get it ?
They taught that way in class
Very useful😍
Dear sir, what is the role of amplitude with respect to source and receiver movement.
Help me plz
I'm looking for worksheets ( phy Cambridge 9701A& As level)
I could've wrestled my way with all the different variables, but I would not have caught the importance of the signs on the numerator and denominator. Thanks!
is this for igcse physics?
Just so awesome bro, impact, change and mordenize. Keep up🤝
I understanded in 15min
Even though I'm takeing privet classes shame on teachers who doesn't deserve to be called teacher
What if both Observer and Source are moving toward one another.. Anyone with an idea.. Or if both are moving away from one another
Awesome 💙
If a car honks at me twice while coming to me, and twice when it passes me; would the time between honks be smaller when it is coming to me than it is moving away from me?
Thank you so much 💙
The doppler effect heading looks like a minecraft boss
omg I finally understand this concept! I got this practice question right. I feel really great about this.
wow, 2 months later you got an extra million subs
In the 3rd example, is the the car not moving west and the driver moving east , is that not in the opposite direction which will decrease the value of the Frequency??? Letting us use -vo and +vs
Real one... stopped me from committing harakiri - this stopped me from hiring a hitman for my physics teacher on the dark web fr fr on g
💀💀
Hello, This lesson is very useful, I extend my gratitude to you. But if possible tell if we can have Doppler effect if both source and observer are at rest?
No
no, because doppler effect is caused by relative motion between the source and the observer
I wanna say thank you
But it doesn't have side effect watching everyday instead of studying?right
And I'm afraid I'm going to finish all the maths that I need to study in the next decade in one lockdown year. Then what studies? Hahaha.
You are the best teacher 🫶🏻🫶🏻🫶🏻🫶🏻
Thanks❤ it very helpful
But My teacher added winds 🙂
u make me want to not attend classes anymore, what's the use of going to class if i could sit in my room and understand everything from your videos😭😭💗
My best online tutor! 😌
PEM students were are you
What do you do for a living? Because you are absolutely needed in academia!
At long last thanks to ur video l hve finally understood this shit. Thanks bro
