Where do bad rainbows go? To prism, but it's a light sentence.

[jalanjalantravelandtours]

Thank you for this short and simple explanation it answered my 4 year old son question about how rainbows are made.

[MrRoccoMarchegiano]

My good lord. That's well better than my teacher back in school. I didn't realize how well prism actually refract....damn. Nice. I gotta set one up permanently now.

White As Alien X because Alien X have white ( Ben 10 Omniverse ). Black skin is also beautiful.
Prism As Contumelia because Contumelia can appear in any shape ( Ben 10 Omniverse ).
Red As Arishem because Arishem is red ( Disney's Eternals film ).
Orange As The Real Creator Of Galaxies because there doesn't have to be only cartoons.
Yellow As The One Above All because The One Above All is yellow ( By Jack Kirby ).
Green As Drago because Drago have green eyes ( Bakugan Battle Brawlers ).
Blue As Mr Litwak because Mr Litwak have blue eyes ( Disney's Wreck-It-Ralph film ).
Indigo As Rick because Rick have blue hair ( Rick And Morty ).
Violet As Ultimate Zeno because Ultimate Zeno have purple skin ( Dragon Ball Super ).

I’m desperately trying to put this up in my bedroom as a wall decoration (read: Floyd fan). Just not able to get that focussed beam of white light. Can you please help me out with something I can buy off he shelf. Or should I use a combination of lenses and make it.

The rainbow "is" the pot of gold.

Great explanation...short and concise.  Thank you for posting! :)

You have never paid attention to a musical Cd n front of a window; it also gives you a bunch of colors; and the light is not going through it like in a prism. It doesn’t look like the light is made of so many colors, but instead, like as it is weakened it turns into a different color. In fact, there are some switches that regulate the power of electricity; and with it, you can make a bright light lightbulb become almost red when most of the power is reduced on its filament. And from red will become orange, then yellow, and finally very white.

What is the white light source in the first prism image? I'd be interested to know if sufficiently collimated light can be produced from an affordable artificial source...?

[michallesz]

Light the lighter and you will see the color of the flame without the prism.

[DonaldSleightholme]

if you shine while light from a light emitting diode through a prism would you only see blue and yellow colours because white light from a led is made from blue and yellow phosphates? 🤔

In this experiment
Is the surface acting as a screen? 🤔

what kind of glass is the best using for a prism

Thanks a lot.Keep going. Esi from Iran

My glass table sort of works as a prism it only separates green light tho

[jeffreykalb]

Nice illustration, except it's wrong. Listening to too much Pink Floyd... Light does not show distinct colors inside the prism. In, fact, the light leaves the prism white and only thereafter is distinguished by color, beginning on the edges and gradually moving toward the center. Goethe showed this conclusively 230 years ago, but we keep copying the same faulty diagrams, never doing the experiment ourselves.

[John-ppjr]

The explanation is wrong.
The white light is also dispersed at the first air to glass interaction. White light does not travel through the prism and then get dispersed at the glass to air transition. The white light is dispersed at both air to glass and glass to air transitions.
