You are telling what and how and what but not why. Why are there different kinds of events? Absorption: light pushes electron to a new quantum level (changing the state of the atom). Reflection: light pushes electron to a new level but electron bounces back and sends out a similar wave (temporary absorption) Transmission: electron is not able to be pushed at all because the light doesn't have enough energy.
I study art major to avoid math and physics, but turned out I have to study how lights reflect on each objects including gummy bear and now I'm crying at how bad I am at both art and physics. Very helpful and easy to understand video tho! I love it!! :D
It'd be too complicated to explain and would lead you down a whole path of videos lol it's basically an electron that is either increasing or deceasing it's orbit, around an atom producing longer or shorter wavelengths
@@Abc-tx4zr not too complicated to explain, I used to teach spectroscopy in a museum when I was 12. They didnt have age restrictions on volunteering at the time, so long as you knew the material. And you watered it down to the point of being sort of wrong (no offense). Basically, this is the subject of spectroscopy, and googling the term will yield a lot of information on the subject. Electrons around atoms exist in "probability clouds of stability" called "orbitals". To simplify it, electrons require a certain amount of energy to exist in each orbital (you can think of them as shells, some are higher or lower, but that is excluding the concept of suborbitals, which have complicated shapes), and some require more energy than others. Each orbital is pretty exact and specific in the amount of energy required for an electron to stay there. An electron can jump between these orbitals by gaining or losing energy. It does this by absorbing or emitting a photon (particle of light). Since the electron requires a gain or loss of a specific amount of energy, it absorbs or emits a photon of a specifc wavelength (since the wavelength of a photon is related to how much energy it has). This wavelength also corresponds to color. Your eye then blends and averages these wavelengths into one, which you see as a particular color. You can then break that light down into a spectrum with a spectrascope if you want, using things like prisms. This breaks the light down into a rainbow, and if the thing you are observing is either subtracting from the light by absorbtion (like the gummy bears, or the leaf), or emitting light of specific wavelengths (like a neon lamp for example), you will see lines. Colored lines on a black spectrum for emmission, or black lines in a rainbow for absorbtion. These lines are the specific wavelengths of light the electrons in the substance absorbed or emitted. ... And each and every element, and molecular bond, produces a unique pattern of wavelengths in a spectrascope... Meaning you can use a spectrascope to "fingerprint" objects, and figure out what they're made out of, even from a distance. This is why we can tell what a star is made out of without ever having to visit one and take samples. ... The electrons themselves dont have wavelengths... Well, rather, an electron can be described as a wave if you want, as can pretty much any particle, even macroscopic objects, but that is essentially unrelated to the subject of spectroscopy. The only waves you care about in spectroscopy is light waves. You get the jist, I can tell, but that's an improtant distinction that can confuse people.
Really atoms of what make objects virbrate at a specific frequency, light has different vibration frequencies, but the virbration that matches the object will always bounce back. The part of the light sprectrum that vibrates at the same frequency with the object is going to get reflected and the rest that do not match will get absorbed. So what matches has the same polarity, just like magets will repeal.
Wonderful info and wonderful voice! I can see your strengths as a teacher but might I suggest that you SLOW IT DOWN. I'm and old lady of 65+ years who is exploring math and science for that awe I had as a child. You are wonderful but you need to slow it down and let the slower minds, that think while you're talking, who need time to listen and think, about what you JUST said before you speed onto the next teaching moment. I had to watch this several times to get it all wonderfully tucked away. Thank you so much for being light... just don't talk with the speed of it?😉👍
When light is absorbed, the electron is excited and then goes back to the original position, right? So the radiation that it absorbed should be the same as it emits, I believe. So, is this the effect of reflection? And, for the absorbtion to happen, the photon has to have the exact amount of energy that is equal to the gap of which the electron traveled, which is emitted back when the electron goes back to the stable position, am I right? So my question is, how does absorption (and heat generation) occurs? Thanks for the video (and hopefully the answer)!
how exactly is light "reflected" off of a surface? What happens exactly for an electromagnetic wave to bounce off a surface? Does it have to do with refraction, with the absorption spectrum of the medium it is hitting, or another physical principle?
I went on a long bike ride at 12 pm under the sun wearing all black. All I could think about was if wearing black was the best choice. Like, most bikers wear bright green or yellow outfits. I was super confused so I looked it up on youtube as soon as I got home and fortunately found this video. When I took off my clothes I noticed that my skin was fresh and not burnt at all, most of the energy was absorbed by my shirt, not like other times when I went out wearing brighter colors. Rad shit.
In the Fall, Leaves turn from green to yellow to red. I guess that's because the tree is trying to absorb as much sun as it can during that season. pretty cool. Never knew that...
Can you please answer? Is there a material that exists or that we can make that stores this absorbed light and then emits it later in the dark? How can I make this material absorb all the spectrums of this light??
So if I have a have two mirrors facing each other and if it is few centimetres apart, the number of images will be multiple rather than being infinite (I kinda feel weird because I always thought it was ♾)
We really need to change this "Light bounces off another object" explanation. Everyone uses the same example, and in doing so, leaves out the coolest part of what is really going on. Thank you helium73 for... Ehem... Shining some light on the matter. lol. Light isn't a flippin tennis ball.
but how is the light reflected? is there any explanation? for absorption i believe electrons are bumped into higher energy levels or turned into molecule/atom kinetic energy. but how to explain reflection?
Please give an explanation. You gave us good information about the basics, but I wanted know the science behind it, like why the light was not travelling through the red gummy bear like the other ones.
Not EXACTLY what I was looking for. I want to know what about the leaf itself makes it absorb and reflect the colours that it does. I know you said it has to do with the pigment but does the pigment have a frequency of its own the resonates with the colours being absorbed or reflected? Wood, for the most part, is brown. Is that because of the unique vibration of the wood itself? Why a consistent brown when it comes to wood. And consistency in colour with matter like dirt, steal, copper, rubber, etc.
I watched this video to try to answer a Q about something I see. I'll keep looking, but if anyone knows this, Please feel free to explain: It's a rainy, overcast day, and I'm sitting here looking at the windshield of a Tesla with rain drops on it. The drops on the top half are a bright yellow/orange color with a small reddish band below it, but the strips where the drops have cleared look color neutral. (GREAT, the owner just came out and let me look on the inside.) The inside seems to have a very light gray, color neutral, tint on that part of the windshield. I believe this is an example of refraction. Is that right? And if so, what is the difference between reflection and refraction, and why do the drops appear yellow?
If the electrons absorb photons to move to a higher energy level, wouldn’t they de-excite and then give off spectrum? And why wouldn’t that spectrum affect the object’s observable color? Pls i’m really confused rn
That was helpful. Question? When the light contacts the angle of incidence does it increased the temperature of the medium in a linear fashion. Is there a relationship between the angle and the net increase of energy delt with by the medium.
So, it may be a stupid question, but I have to ask it(cause I failed to find answer elsewhere) Why does absorption/reflection/transmission happen? Is it some molecular structure that is responsible for reactions to specific wavelengths? Or something else?
May I ask sth, eventually the reflected transmitted absorbed light are all light that are reflected to come in our eye. I am wondering what is the difference
What causes objects to reflect a certain wavelength of light? For example a lemon is yellow, why does it reflect yellow? My t-shirt is red, why does it reflect red?
The components of your shirt are such that they absorb every color that is NOT the combination of light that gives the red of your shirt, reflecting those frequencies to the eyes of the observer. Is that the answer you were looking for 2 years ago?
+Bozeman science , Please do a vidio explaining the polarization of light , please i have an exam about that , Do your thing explaining this topic please
interesting how nature mutates or evolves to do what it needs like those leafs,,ok you kinda explained absorption and as i figured some of the light or energy is changed to heat but can it be changed to a longer wavelength such as ir etc? and i still don't understand how reflection works on the atomic level what is happening there? as well as transmission ,silly question but dont atoms block the light or cast shadows lol like atoms in glass as opposed to something opaque or solid etc
So some of the blue-protect glasses is yellow color instead of blue color. (I mean the reflected ray we can see at some angle) It's because the yellow color lenses absorbs blue light, am i right? but where the blue light go? turn into heat energy?
When light passes through a glass light of all colours pass through it and make a sprectum.also the portion of light which reflects is not red but white
Can you contact me I took pictures of a spiderweb against the white light and actually caught particles moving reflecting the light spectrum. It looks like tiny threads of rainbow bouncing around pretty cool. Would love it if you can look at them.
what happen when Visible (Vis) ,Infra-Red (IR), Microwave, Radio wave and Ultraviolet (UV) types of electromagnetic radiation with corresponding molecular energy transitions that occur when they are absorbed? I mean how they change ? as I know they change to electronic or vibrate or nuclear and rotation, but I am struggling to know which one is change to those.
black absorbs the most heat, while white absorbs the less. i am trying to find the colors that absorbs the less amount of heat possible besides white.. i hear it’s grey then i hear it red or green, can someone give me a solid straight up answer please!! from white to black which colors reflect the most sunlight PLEASE
I have an existential crisis😂 the leaf threw me off balance 1:26 The color that gets reflected is green why? What is the actual color vs the reflected color?😢
