What is Relativistic Doppler Effect ? How Frequency changes due to Relativity
ฝัง
- เผยแพร่เมื่อ 21 ก.ค. 2024
- One consequence of the Special theory of relativity is the change of frequency (and wavelength) of light due to the relative motion of Source and Observer. This is called the Relativistic Doppler Effect. It is different from the classical Doppler effect of sound, as it involves Time dilation effects resulting in the Doppler effect.
In this video, I discuss a simple setup to obtain the relationship for the Relativistic Doppler Effect for source and observer in relative motion along an inclined path with respect to the line of sight. From there, I use the formula to obtain necessary expressions for Longitudinal Doppler effect (Both approaching and receding cases) and Transverse Doppler effect

Amazing lecture. Loved how you dealt with approaching and receding cases with just one equation, setting theta = 0 and 180 degrees.
Excellent discussion of the doppler effect, for both light and sound, with motivation, examples and lots of detail. Congratulations!
This is amazing, and is much better than most of the other professors' explanation!
You are very great at explaining this, this would be really helpful for my group report. I hope you create a video more about this with sample problems. Thank you so much!
I have seen many videos of relativistic Doppler Effect but I found that this video is very beautifully explained by you Sir so thank you so much for this
Such a beautiful and comprehensive explanation, thank you!
How easily you teach such a beautiful concept in a mesmerizing way . Thank you so much ❤
The most elegance physics lesson so far. Great job. Thx 🙏
Excellent lecture! Clear explanation of the relativistic Doppler effect!
Amazingly clear. Wonderfully done, and thank you very much.
You explained it really nicely, an otherwise unnecessarily difficult made topic in some books and articles. I was wondering if such a video on electromagnetic radiation could be made, accelerating and dipole ones i mean. That I am sure would really be helpful to a lot of people!
What an amazing video sir this lecture had everything in simple but accurate way. And you make it seem so easy to understand
This was the best explanation by far! Thank you!
The way of his teaching is extremely good..I don't know why this person has so little growth in you tube, whereas shitty channels grows exponentially.
All the best brother..keep giving your best.
An amazing explanation. Thank you Sir!
Sir your Collab with SciFi box was fab ❤️🔥...the podcast was lit... expecting second episode 🔜
Thank you so much sir.... You made the concept quite simple🙏🏻
Love your way of explaining and making things easy to understand . Huge respect sir ❤❤❤
Excellent explanation as always . No words for it.
Thanks a lot sir
I have been struggling with the bulky derivation of this eqn in special theory of relativity. But the way you explained is amazing.
Nice explanation as always I understood STR from your videos sir please complete the full series of STR😊
Very nice and simple explaination of complex concept.
Amazing video, very well explained! Thank you!
Huge respect sir . More power to you sir.
Amazing.. I'm from Bangladesh... 😌 A higher secondary (cls 12th) student .... Taking my preparation for national physics Olympiad... Thank you sir ❤
Thank you Sir. Your videos are amazing and very helpful. They make concept very clearly understandable.
Brilliant Derivation! Thank you!
One of the best channel of youtube🤗🤗
_Some kind of a fantastic Physics teacher_
Great explaination....this is what I was looking for
It's an amazing lecture sir I requested you to record a lecture on LHC kindly do it as early as possible
Amazing, thanks allot this helped me with my assesments.
It's really good concept 🙂🙂 and understand clearly,Tqs for this video
Best channel I‘ve found wrt physics, very, very good. Greetings from 🇩🇪 Germany, 🍻 Cheers!
U r so amazing sir ,u make my concept crystal clear really your lecture is too good🙏🙏
Superb explanation 👍👍👍
Very useful video. I've struggled with this effect a lot, but you made it so clear, that now i understand it. Thanks a lot :)
What are u doing in life now?

amazing explanation thank you
Wonderfully explained.
Thanks sir for this crystal clear explanation 🙏🙏🙏🙏🙏
I learned many concepts because of you sir ❤️❤️❤️ thanks a lots 🙏🙏❤️❤️❤️❤️❤️
What a magical explanation.
very well explained, tysm!
thanks for wonderful video
superb sir...u just rocked the session❤️
Excellent sir.
your explanations are really nice👍
Thank you sir making physics so functional
All clear sir 👍👍 very good explanation 👍👍
Perfect.sir kindly teach electrostatics and magnetostatics also in this way.
Amazing lecture sir 👌 👏 🙌 😍
thanks a ton sir
u are very nice teacher
Beautiful!
Thank you so much sir😇🙏
Amazing!!
Thanks sir very much
Thank you so much Sir 😊🙏🙏
So under rated
Just waooooo ....amazing
Just excellent.
Great sir
show that the net magnetic ploes strenght of a magnetized material
Respected sir .. plz is ka ans bta dain??
Thanks sir ♥️
Sir, kindly suggest some books on partical accelerator
very good. Did you do relativistic beaming? thanks
Sir i am unable to understand how you are saying frequency is inverse time duration between the signal . Why we are taking signal one and two time difference sir . Means the first signal will have some frequency right sir ?
Superb
Excellent
Does relativistic Doppler effect applicable on partical nature of light??
Amazing sir
Best channel😍😍😍😍😍😍😍😍
Very good 🎉🎉🎉
But: if you pull down the two L lines exactly from their starting points and exactly(!) to the g r o u n d there is no difference in length. They are necessarily equal. The picture seems to be ad hoc and somehow flawed. v d t prolongs the first distance only bc the second is detected at a greater height, right? So, how to bring theta into play in the true case?
Wow 😲 sir
Thank you for exama
Giveaway result??
Bhag edhar se padhai karne aaya he yafir giveaway jit ne aaya he
This is how every teacher should be
Thanks
thank you
Nice nice ...... sir when the results of randomly selected students will be publish
good sir
Wow I got it perfectly
Hi sir, please include twin paradox into this series
Is channels name ispired by Walter Lewin sir?
Sir can you pls explain this qn from nuclear physics.despite of nucleons constantly emitting and absorping pions why they are not found other than their usual mass.
It is because both have diffrent isospin.
Sir main bsc kar rahahnu uske liye notes chahiye concept ta clear hogaya lekin.... Exam ke liye
Real Physics Love❤️
The doppler affect is just that, an affect, not a cause. The cause of red shift in all cases is gravity. Gravity as the photon struggles out of a star or galaxy, the gravity as the photon joes past and through gravitational geodesics, AND as the photon moves head on towards you. The photon presses against the space, the aether, and the aether presses back preventing it from traveling faster than "C" as well as causing the photon to lose energy by way of a change in wavelength. This change in wavelength also has an affect on relativity. The photon having slowed down internally experiences time slower than an outside observer.
Giveaway ka wait kr raha tha sir
Giveaway nahi hoga kya
sir , why did we take theta as zero degree in approching case ?
Well that's a pretty nice one I'll admit, but think like this if you have heard about "Blue shift" and "Red shift" and what happens when the emitter comes closer the frequency increases right hence theta must be 0° otherwise just try putting some value of v and taking it as 180° you'll find that the frequency will decrease which isn't possible that's why we take it as 0°. Btw I know it's been 2 years you might not even be on the same page of life but if you read this one what are you doing in life?
Sir please solve questions on this
Sir, I'm in 9th grade and I'm currently learning about gravity and I don't know much but I want to ask why do planets rotate?
Figure it out yourself. This'll help a lot !!
Planets rotate electrons rotate to attain stability in their motion their spin angular momentum maintains the orbit and its energy and oppose any change in angular momentum that means it resists applied external torque
how does the wavelength change?
Well the wavelength changes in order cause the frequency does and the speed of light (example) stays constant imagine you emit a red light and come close to me now the frequency will increase as we call it Blue shit, also the wavelength will decrease keeping the speed of light constant c= wavelength × frequency. It's been a year but I hope it helps you.
Sir Giveaway date?
Kb hoga Giveaway
Try to cover Transverse Doppler Effect in detail, it is not that obvious as you know
Why does it occur?
1 week ho gya hai sir
Giveaway kb hoga
