Roses are red, or are they? [Vsauce music plays]
Hey vsauce Michael here, and in honor of Valentine's day, we're talking about roses. Now, as the proverbial poem goes, roses are red, but what is red? What even is color? Well color is merely our eyes' and brain's interpretation of photons with a specific frequency...
I had fun writing this and I think I'll compound on it later to make a complete copypasta
Ah, the Doppler effect. Same reason why sirens of emergency vehicles appear high pitched when moving towards you but lower pitch when moving away from you. It's due to the compression or stretching of sound waves in this case which is perceived as pitch. Interesting stuff indeed.
In the case of light, red light has a longer wavelength than blue light. So when something moves away its light is red-shifted because the light waves coming from it are stretched out behind it due to its relative velocity from you. When it moves toward you the light waves compress so it is shifted towards the blue end of the spectrum.
Could this be experienced in real life? I mean, is it possible to go fast enough on earth to get this affect in the visible spectrum?
No. Not for a physical object that you can see right here on earth.
Black holes also exhibit the Doppler effect
The universe as well.
Oh that's how that works, i never really understood the doppler effect
Doppler effect also applies to light? Damn thats cool to know.
Thats what i came for. Thankyou
K just for fun lets say this hypothetical rose could get going fast enough to cause this blueshift.. how wrekt would we be if it grazed the atmosphere, and or straight hit the planet.
Would the rose vaporize long before any damage was done or we looking at some sort of catastrophe?
The rose would not make it through the atmosphere. A full blue shift from like 700nm wavelength light to 400nm would require absurd speeds, and the rose would at the very least burn itself up in the atmosphere
The energy still gets dumped into the atmosphere, heating it up.
Everything is every color ...isnt it? Just different values
Color is not a physical property...only our observation changes
How much of observation is reality
Are you a physicist? This seems like something a physicist or an astronomer would think about. I'm here for it
No, this is Patrick.
Roses are red, Violets are.. VIOLET dumb ass
Truly clever... +1 for you.
One shift, two shift
A shift, B shift
Land shift, sea shift
This. This I like. +1
super clever. take my updoot
yes, I like, I find that funny, I will updoot.
Although in order to cause a visible shift in spectrum (especially to blue) they would have to move so fast the air resistance would destroy them (yeah vacuum whatever), so let me ftfy:
Roses are red, not really blue, in order for them to be, you would be too.
Bravo! I can't remember the last time I heard a good Doppler shift quip.
