Doppler effect

Gotta love it. There are a ton of fun cases where this pops up in everyday life, most commonly with sound. It's one of those things in life that make you go "NYEOOOW" and you feel really cool doing so. However, that isn't the only thing that the Doppler effect is known for. One neat trick is that the Doppler effect applies to visual light as well. You may be saying, Well I've never seen it work like that before, and that's because it's a bit too small for our regular human scale. We use the Doppler effect on a larger scale- thinking about stars and how they move relative to our position. A redshift means that the object we are observing is moving away from us, stretching the length of the waves, making the frequency lower. A blueshift is when the object is moving towards us, and it causes the opposite effect. I've seen a few videos of people throwing speakers like they are in the Olympics (like they spin around a bunch of times with a speaker attached to a rope, and then they let go and let the speaker fly), and it would shock you how anti climactic these videos are. The main reason is that they often position the camera and thus the microphone where the person is throwing the speaker, so you only get one half of the Doppler effect, the part where it pitches down. This is a travesty and is probably the result of rage bait directed towards me. If I see these types of videos on social media, I will usually block the accounts associated with them and tick the option that makes it show less of that kind of video. It's cool to see the Doppler effect recreated in video games. If you've ever played Mario Kart 8, you would know that if you don't have an item ready to be flung at whatever poor sap is in front or behind you, you can press the item button to honk your horn. It is often very funny to honk your horn at your opponents as you pass them because the developers added a Doppler effect to the sound, and so it sounds very funny being passed by someone with the good humor to honk the horn. I wish there was a character in Mario Kart whose horn is the La Cucaracha horn, because I think that horn is very funny, and is often associated in my mind with the Doppler effect. Maybe because of Ed Edd and Eddy? One of my friends once called the Doppler effect "the doppelganger effect". This is an honest mistake that any average person could make, so of course this instantly became a bit we would rip on them for years to come. The doppelganger effect,,, don't make me laugh. Forget the fact I also accidentally called it the doppelganger effect but none of my friends caught on and thus I was not the target of their ire. I recommend going for a walk if you want to hear the Doppler effect. You may often come across someone driving their cars with the windows down, and if they have music on, you can hear the Doppler effect in full swing. There have also been many times where this music has been replaced with a blaring police or ambulance siren. I don't like those as much, and because of that I am docking one point off for the excessively loud noise. Still, I think the Doppler effect is a wonderful thing to exist in our world for the most part. It makes me smile that the universe has the humor to let stuff like this exist.
