Thanks to the narrator who explained how we are perceived colors as light waves--it is stunning that human eyes are designed to decode those visible light wave and send it to the brain to recognize as a distinctive color.
This is amazing. I just learned today that there are colors our cones or color receptors cannot see - they're called Forbidden Colors! Colors we cannot see. Colors we haven't named --- Colors we haven't and probably will never discover. Think about it.
"do they convert the wave lengths that are usually out of our spectrum in order for us to see them?" Yeah, you can say that. In order to see the picture we must use visible light, yes.All you need to do is to multiply or divide the values, so you get wave lengths you can see. The cool thing here is that there're more colors than we can experience and see. There are more colors than we know. That's quite mind blowing, actually.
Not more colours, just different wavelengths. Remember, lights doesn't have colours, as they are an addition of our brain. Everything outside of our soectrum just wasnt assigned a colour, because we cant detect in anyway. There is however nothing to indicate that the brain would make up a new colour for different wavelengths. All colours are made up by the brain and fitted onto the wavelengths you detect. We dont even know how the brain is doing it, or why its using colour specifically (since it could use basically any sensation to represent wavelengths). Extra fun fact, you CAN use different sensations to represent wavelengths by rerouting where the input is processed in the brain. Light only gets visible because its processed in the visual center of the brain. It can however, be processed in the auditory center and hearing it works just as well. Vice versa that works too. Thats how people on certain psychadelics can taste colours for example. Its all happening in the brain, colour is not a physical phenomenon, and not a property of light itself any more than pain is a property of a hot metal rod.
Light can be powered by thermo-nuclear fusion like we see in stars, however their are other ways to power light like nuclear fission, chemical molecular reaction, mass colliding with other forms of mass, etc., etc. Light particles/waves can move so fast because they have almost no mass, making it relatively easy for those waves/particles to move at the speed of light.
Shoutout to the James Webb Space Telescope. The fact this video is 9 years old but still here to be pushed back into the UA-cam algorithm, might we well. Let’s make more telescopes! 😄
They simply use a color code to shift the light back into the visible spectrum. You've probably seen this in weather maps on the news, that's just radio waves which are then given a color code. The same thing can be used for infrared (IR) or Thermographic cameras to see heat.
Very good & witty explanation. I want to add one thought: Walkowicz calls radiation "kinds of light"; I'd like a quick clarification - "we say x-rays, microwaves, light, etc. but they are waves, so we'll call it 'kinds of light' for this talk".
the energy comes from various places. sometimes it's an electron jumping between orbits with the difference in energy being released as light. So if one orbit requires 3x energy to be in and then the electron drops to an orbit that requires only 1x energy, light with energy 2x is released. And it moves so fast because it is massless and everything that is massless moves at the same rate (popularly called the speed of light)
I think the idea of the video was how blind we are and how much we cannot see. If we evolved differently we could maybe see magnetic waves, gamma waves or radio waves. They say the amount of the Electromagnetic spectrum that we can see, if you extended it from New York to Los Angeles is only the size of one single golf ball. That is completely mind blowing.
The question i asked was why we can't see object smaller than wavelength of light ? And youtube recommend this video ...We think we know so much because of videos like these just giving pseudo satisfaction.
light waves are usually shown as being vertical like this ~~~ or vvvvv I suppose that in reality light waves are more complicated than this. They must overlap and coincide and meld and mix and interfere.
that is true. also, when we see colors, we are very rarely seeing one color. other than pure red, green and blue (i believe those are the three...), whenever we see a color, it is multiple wave lengths of different colors. they are put together and viewed as one color by our brain. pink, yellow, orange, magenta, they are all just different ratios of the red green and blue wavelengths that our visual system translates into one smooth color. it gets much more complex than what this video (or i) describes.
I know that there are a few other replies to this, but I think this one is better. Imagine your favorite song, and imagine you play it at 1/100 the speed. The pitch is lowered and it isn't likely to be recognizable. But if someone in the room records it in full, and then speeds it up by 100 times, they will essentially have the original track. In the same way, if the frequency of light is too high for the eye to see, they will stretch it out until it is in the visible spectrum.
We only call it light because we can see it. It is a human made concept. In fact what we see is a part of a spectrum so small if you extended it from New York to Los Angeles would be the size of a golf ball.
Those are the mathematical simulation of how a wave looks. They're used because this is how physical waves look. Look at a body of water to see what they mean. Does light actually move like this, nobody is actually sure but it's close enough to explain things.
there's a special relationship between water and microwaves, which causes water to absorb energy from microwaves easily. Think of how a black shirt collects far more heat in a sunny day than a white shirt does. It's an almost identical effect.
Came here being quite aware that there are facets of reality not readily apparent. Unfortunately, many seem to be under the impression that they have all pertinent information on reality.. while being blind to most of it.
I do not know it but i guess you have to edit the pictures (on a computer) by multiply the wave length. Lets say you can see from 1 to 5 and you want to see something between 0 and 1, then you simply multiply every value below 1 with 5 and got a value you are able to see
I think light is visible when it hits particles and we can't see it passing through if there is no dust flying around but if it hits anybody it becomes visible
Thank you, and the Science makes sense..there are missing pieces meaning.. some frequency of light and or sound certain animals and human can pick up and others can..lets say like invisible energy as ghosts or photonic energy... some gaps on info. Need to be filled,.but great video 👍
bro when she was getting abused my the wine bottles and the soup cans at 1:45 I realized that the whole video was her hallucinating because she had too much booze like and my teacher assigned this to children
Kinda disappointed that you didn't include a picture of the spectrum. It really puts into perspective just how minuscule the visible light spectrum is compared to the rest of the EM spectrum.
I wonder why we have all kind of uses not directly related to seeing for the invisible vawe leghts, such as microvawe or radio, but we only use visible light for seeing? Why there's no other useful characteristics for the visible light, but we have found these other uses for the wave lengths of the light we can't even see? Haven't we just figured them out or is there simply none? 🤔 Also, not seeing some wave legths doesn't mean we wouldn't see items that have these colors (we wouldn't be blind to them)? But we should see them just as different color. For example, many animals have colors we can't see (but these animals can), and we still see them. But the invisible wave leghts seem to not just change the color, but actually have additional information, such as internal vision to human body. The wave leghts we see are just colors, but the other wave legths seem to be "more" than just the color. I kinda don't get that 😄
Well, lasers are made out of concentrated visible light and it's pretty useful. Also, not seeing some wavelengths ACTUALLY mean that we wouldn't see items that have "those" colors. We humans are trichromatic beings whereas creatures like a certain type of butterfly, etc, have tetrachromatic capabilities that allows them to see different colors than us. Our eyes has limits and we can't see something that's beyond our eyes' limits.
@@andranohitipeuw5543 thank you for the reply! I was actually just thinking about these questions again the other day. I wonder if we could use visible light to send messages, such as radio waves, or if we could use it to understand structures, such as x-rays, for example? Or are these only characteristics of the certain wave lenghts? And also if we could use the invisible wave lengths to make a laser? Is it just a coincidence we use different wave lengths for different purposes, or do they have specific characteristics that make them very different in physical realm? What are these characteristics? Also, I was thinking about the example of a colorblind person. They have limits on their eyes, certain cells don't work. If you can't see certain colors, it doesn't mean that for example certain stripes of a ball are literally invisible to you, but you see them as different hues. Is this phenomenon somehow yet different from the certain wave lenghts being invisible to us? How?

If an extraterrestrial, who could see the whole spectrum of light, compared his vision to ours, he'd say we're almost blind :/
Actually, colors only exist in our minds. There are no colors we can't see, only wavelengths of light our eyes can't detect.
ok boomer
lmao did anyone else come here becase their teacher needed them to watch this for an assignment for school
Yeah
I knew about the idea of this brilliant UA-cam clip, but perceiving of different colors which were mentioned on this clip, was very important!

whn the light hits our eye, the relative amount of energy each cone of the retina measures, signals our brain to perceive colors.

Unfortunately, many seem to be under the impression that they have all pertinent information on reality.. while being blind to most of it.
the waves of light and colors are like waves of the ocean. it could be big or it could be small. this size of wave is called wavelength
Thank You for sharing this video, very insightful ✌️

I do not know it but i guess you have to edit the pictures (on a computer) by multiply the wave length.
Lets say you can see from 1 to 5 and you want to see something between 0 and 1, then you simply multiply every value below 1 with 5 and got a value you are able to see
I think it depends. From electricity (bulb, lamp, traffic light,etc.) or thermonuclear explosions ( solar energy).
The way the narrator says "wave" reminds me of a very subtle Bermudian accent
awesome, small detail in the rainbow shot when there is a double rainbow the "inner" rainbow had is colors reversed
I think light is visible when it hits particles and we can't see it passing through if there is no dust flying around but if it hits anybody it becomes visible
