I know this may be physics, not chemistry. But I'd like to say thank you. I'm a year 10 in year 11 chemistry and I have my first test tomorrow. I've been kinda stressed but these videos explain things in a simple, yet effective way.
@@Cognitoedu trouble is calling light colours is wrong, colour doesn't happen until it gets into the brain, the universe is grey. rods and cones detect energy levels and colour gets assigned later, light coming into the eye has no intrinsic colour.
It’s because in physics it’s usually about the actual waves of light being emitted such as on a screen however in art pigments absorb every colour except the one they appear as. So if you mix all the primary colours in art it becomes a black-brown colour since many different wavelengths are being absorbed, but in physics since it’s talking about the act light not an object or pigment when all the primary colours mix it appears white
Do u know how many annoying kids are there in my class i cant hear a single word my teacher said so i have to bring my book from school and spend the evening listening to this masterpiece and write notes from what i missed today now i have like 3 chapters to write and catch up on this guys is a legend, thank you ❤
Actually, the spectrum doesn't go all the way to violet, it stops at blue. If we don't have a cone in our eyes for the colour we're looking at, we tend to see the colour in between two of the cones we do have, e.g. if we see red light and green light we might interpret it as yellow light. But in between blue and red on the spectrum is green, and if we happen to know we aren't looking at green because our green cone isn't firing, then our brain invents a colour, which is how we see purple.
Keep making these it helps at lot thank you so much for your time. I have an app that I use to download music and I download your videos onto it. I listen to the ones I tend to forget or struggle with every morning before I go to college and after college as I have a long journey, its helps me remember. I’ve been doing it for almost two weeks now and I also revise. I was doing triple science higher but I recently moved down to combined higher so I’m really just trying to do the best of my ability and aim for a high grade to move on. Why not?🤷🏾♀️😊
yellow is but in light its not and green is, yellow is a primary color because blue and yellow make green, the primary colors are blue, red and yellow.
I have a really big test about this tomorrow, and I didn't understand anything, but you helped me understand in less than 6 minutes! ( You saved my grades ). TYSM!

What about someone with brown skin like the actor Denzel Washington. Is his body reflecting brown wavelengths?
isnt yellow a primary color instead of green, cuz green can be made from blue and yellow?
Weirdly the primary colours differ between art and physics. For light, the primary colours are red blue and green
@@Cognitoedu ohh alright thanku!
Remember it as RGB red green blue
u probs dont care now anyway tho after 2 years

I didn't know that the primary colours changes when it comes to physics-

It’s summer break for me. Just studying for year 11 haha.

Mine lol
my teach did
Barakallah. Thank you so much, this video was an amazing ❤️❤️❤️🥺🥺
@Cognitio i thought red and blue wavelengths made magenta wavelengths not indigo....idk
Simply amazing… you have an amazing ability to explain things and make it so easy for the students 👏🏻
i love cognito my genius king never die bro never die
awesome video! keep making them, it really helps a lot
Thanks for the comment and really happy to hear you found it useful!
yellow isn't primary colour ? i thought it was
yellow is but in light its not and green is, yellow is a primary color because blue and yellow make green, the primary colors are blue, red and yellow.
got a 8 in physics in my gcses in 2023 and for some reason our teacher never taught us this so im having to learn it now for a levels
Its 6 .30 and 8 ,o clock I'll be in school giving my paper 😂😂😂

D:
Please make A- level videos
How are other colours made which are not on the spectrum
A bit late but white is made from all the wavelengths (colours) being equally reflected and black is made from all wavelengths being absorbed
