I would explain "why emerging light is white instead of color spectrum?" differently. Since the placement of 2nd prism is in opposite direction to the 1st, now red light travels longer distance and violet light travels shorter distance which contradicts to what 1st prism did and this nullified the spectrum effects caused by 1st prism giving back the white light.

I can't belive that I found such a nice video Earlier I was searching a lot on youtube that why dispersion happens in prism and not in glass slabs . I watched a varities of videos but none of them could make me undetstand as this single video made me understand the whole concept . The key was that light was a collection of many rays so thats why it appears white
But does not a rainbow show a continuous spectrum and not just a series of discrete colour bands? It is our optical perception that gives us images of the recognisable colours.
Very nice and useful video and illustration. I was trying to find a suitable video for my son to recreate for his year 3 school science fair. I found this particular video immensely useful. Thank you very much.
I don't really think the rays will emerge as a parallel beam.. because when going through the gap, the different colours will get separated due to refraction... In short, there will be just a little separation of the spectrum
Suggest reading Opticks by Newton. His descriptions of his experiments are quite easy to follow (and replicate) -- no conjecture is required regarding his thought process.
Black colour light don't exist in nature. Everything you see in black is actually absorbing light thrown to it making us a perception that object is black.

I pray that, this channel will shine like vibrant colours

Great explanation Sir Mahesh! Continue making great content!
This video is the best to clear the theory of colours of Sir Isaac Newton.....!

Very understanding thanks

Actually we were reading this for our board exams😂😂😂
I'm also understanding it for my exams nd for the personal knowledge..!😄

Mahesh sir what if the 2prisms are placed at a gap as in ncert text book will again the rays emerge parallel to each other
Yes :)
@@KhanAcademyIndiaEnglish sir what about refraction..will they not refract towards the normal as it move to glass through air?

Good explanation

Another great video! But sir, I wanted to point out that you have forgotten to include the "Formation of rainbows(&how far are they)" in the playlist.
Great Explanation ;; Thanks
Haste muskuratein jeevan jeyoo kyuki zindgi na milege 2 I 2
It was very helpful thanks
Tq so much for the great explanation
I just understood the whole topic
which board do you use sir, just asking out of curiosity?
This video was very interesting to watch and you explained very well!! Thx.
Thank you sir
Great explanation
It's 6 colors not 7 , 7th was asked by the church to make it more "godly"
I like this voice
good job mr newton
amazing contenttttttt
use a red laser to check
??????????????????????
Nice Video
😂 can we make black colour light?
I think it is not possible??????

brilliant thanks ❤️
He sounds drunk
Brilliant explanation though
Great explanation
