Doppler Effect

108 - Doppler Effect

In this video Paul Andersen explains how the perceived frequency of a source depends on the motion of both the source and the observer. As a source approaches an observer the frequency will increase and as it moves away it will decrease. The same will occur for a moving observer. All waves (sound, water, and light) will experience the Doppler Effect.

I know this isn't AP Biology but I have to let you know that on the AP exam yesterday, your videos helped so much, especially on the FRQs! I was the only one in my class to finish, thanks to you!

NOTE: Mr. Anderson's youtube logo is an example of the doppler effect :P

[WithASideOfFries]

Perfect timing! I have a test on this stuff tomorrow; thank you!

All the light that he saw was moving toward him!
All the light sources that he saw were moving away.

You are amazing at explaining things!!! Thanks

[aishaalblooshi]

Beast explanation ever, and beast physics teacher ever! Thank you 😊

[niroshiniindima]

So much more easier to do Doppler effect sums aftr watching ur video. Thank you

[rachelanndorough]

This made way more sense from your video! Thank you.

Best Video found on youtube, subscribed!

Thanks you much for your videos man.God bless

Carson, isn't the doppler effect this?

I watched this video in science physics. Well now I am a graduate and understood most of it except the color spectrum. Would you be available to
Make a video in more depth to help people like me understand?

I perfectly understand this effect and how it applies to sound, but why does it applies to light? Relativity sais that light always moves 300.000 km/s away from you, even if you travel at f.e. 200.000km/s. So how come the doppler effect also takes place with light if it always moves at the same rate away from you/to you etc...? I hope you understand where I see the problem here

So, does Doppler radar mean we are talking about some sort of stationary antenna that is measuring the distance between moving storm airwaves...or something else?   How does that work I wonder?  Now that I understand the Doppler Effect better, I am curious to know how the radar would work...hmm.  Thanks for the lesson!

Doppler Effect states that the frequency of microwave will be higher if a person runs toward microwave oven. Since the amplitude of this microwave does not change due to standing wave. The microwave actually become faster to the running person.

Would this kinda explain sunsets ? Or this has nothing to do with that?

[fishchronicles]

i want to know if your in the car when it's honking, what would you hear?

[LawatheMEid]

why the sound wave that occur from moving source don`t gain or loss a speed equal to the source speed ..maximum speed in air is 330 m/sec why is this limitation?

[PranjaliGupta]

is this why the in the evenings the sky looks blue and during sunset it looks red?
