Our physics teacher showed us this video today to explain what the Doppler effect is.
The Doppler effect (or the Dopplershift) is the change in frequency or wavelength of a wave for an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.
I always remembered the Doppler effect from dewy in Malcolm in the middle as weird as that is
Mad skills
Playing lower notes as you slowly ski past the camera doesn’t illustrate the Doppler Effect very well. Although I will admit you can hear the shift right after he starts playing lower notes.
This is a better video of the Doppler effect.

That’s pretty crazy
Our 8th grade science teacher demonstrated this by driving his minivan around the track while honking his car horn. All the teachers who’s classrooms were adjacent to the said track hated him for the rest of the week.
Isn’t it forbidden in ski resort to play loud music, scream, …? The problem is not on the ski slope. It is the marke-off area where ~~lawines~~ avalanches can happen.
Or mini-~~lawines~~ avalanches from snow on rooftops. A small child could get stuck, etc.
The ski resort owner want to cause ~~lawines~~ avalanches in a controlled matter so there are no unexpected accidents. (Clearing snow from roof, so the roof does not collapse under the weight. Removing excess snow on the resort so a ~~lawine~~ avalanche cannot happen uncontrollably.)
edit: thought lawine was an english word. It is not.
He changed notes. The best way to explain it is a siren driving by.
That mouthpiece has got to be SO COLD.
When I was at school they taught us the Doppler effect with the example of the sound of the train, the train coming closer to you and going away from you.
if he falls he won’t have anymore teeth
Isn’t this faked
Why was I waiting for someone to be chasing him and yelling, “I want my two dollars!”
Just make the sound of a motorcycle passing by. NNNNNNNyyyyeeeooowwwmmmmmm
[This is also a cool example of the Doppler effect.](https://youtu.be/seget3zOj_8?t=11)
Hell to the fucking no I won’t be bamboozled by this bullshit
Instead of a fake example he could have shown a clip of just about any motorsport or a sportbike flyby.
The ice cream truck passing me by was the most memorable example for me.
Do you know how goddamn hard it is to play a cold trombone? Even moreso while *skiing*.
Also this isn’t all doppler effect, he went down an octave.
[This](https://youtu.be/VeIG76cghJQ) would have sufficed.
I see, so the universe *is* expanding.
Must be a shitty teacher because I still don’t know what the Doppler Effect is.
Thought for sure it’d be [this.](https://youtu.be/xO4LaAHJqxw)
Even better example of it here!

I actually had a physics exam today and red shift/blue shift was in it. And now I see this video.
this is my favourite doppler effect video:

Too bad the quality is so bad, I dont remember it being so bad… think youtube is lowering quality over time on old videos…
your teacher should have used this video https://youtu.be/FjCOJOFBruQ?t=29s
Story time! Back in highschool, me and my gaggle of friends were walking along down town. A group we considered our rivals cruised past in a car, one of them yells as they go by
“FAAAAAAAAAAAATS”
We are all slightly confused, we look to our large friend who shrugs.
“I think they just called us faggots… That my friends, is the Doppler effect.” He says
And that is the day I learned of the Doppler effect outside of school, and made it much easier to grasp once we got to learning about it in class.
[Probably my favorite example of this](https://www.youtube.com/watch?v=H04F_cFktag)
But does it [brrrrttt](https://youtu.be/NvIJvPj_pjE?t=1m1s)?
Getting assaulted by Hueys, playing Fortunate Son, in Battlefield Vietnam, is what taught me the doppler effect.
A trombone playing skiier.. Just your average day on reddit.
This is literally fake. The guy changes notes even before passing the camera.
He wasn’t moving fast enough for that much of a change, it’s either edited or fake or he deliberately changed to lower notes..
Yea, he changed notes. That’s a bad example. A single note of a race car going by is a better example.
Our teacher got us out of the clasroom and we went into the football field. We were there playing a game. One of us would run towards the group with a speaker that was playing music and then run past the group.
We all understood it.
Then our teacher said to all be quiet and gather around so we did, and a fire truck was heard racing down the street and it basically illustrated the same thing. And we all went ahh!.
Then a motocycle was heard and we were still all gathered around so we listened to that and it becase really obvious what this thing that we had all experienced before was.
And that was that. I will always remember it because we went outside running and we all wanted to take turns running around. To this day as I’m at a light or whenever and I heard a police car, fire truck, ambulance, loud motocycle, whatever, I always remember that class, that teacher, my classmated and the doppler effect.
Having played the trombone in marching band and bashed my lips countless times running into things, this video made me cringe. O_o

If you want this to be successful it needs to be the same pattern like a siren or engine.
1. I think this would be considered a ‘demonstration’ of what the Doppler effect is, not an ‘explanation.’
2. This isn’t even a demonstration of the Doppler effect, it’s just someone playing lower notes. So it’s probably more confusing to students (who probably aren’t already familiar with the Doppler effect since they’re being taught about it). The Doppler effect is the shift in frequency due to the relative movement of the source and observer. This shift is due to the source actually changing the frequency of the notes that are played.
3. If you’re “24 yrs old, $200k/yr with $1M in the bank,” why are you only just now learning High School-level Physics concepts?
