Why Is A Rainbow Curved? | Newton's Apple

Ira Flatow and our physics friend Jack demonstrates how rainbows work and why they refract using light.
Hosted by Ira Flatow, Newton's Apple was an American educational television program about science produced and developed by KTCA of Minneapolis-Saint Paul (Now @Twin Cities PBS ) and distributed to PBS stations in the United States that ran from October 15, 1983, to January 3, 1998.

[@9spiderlegs]

This is the best explanation I've seen! Thank you!

[@BlackMcAllister]

So the sun is a laserpointer?

[@ktursts4088]

definitely not

[@tiortedrootsky]

Its pretty good, but check out Phisics girl. She went a little farther and showed how the 42 degrees is happening because its the maximum angle, that the red light can escape the droplet in that direction. Red light that enters the droplet a little closer to its center has more acute angle of reflection, the light that enters farther from the center reaches maximum 42 degrees, and the light farther away gives more acute angle again. So more red light goes out close to 42 degrees. Also she showed how for different colours, this maximum angle is different, for purle its 40 degrees.

2:38 the Carl Sagan impression was spot on lmao

[@RawDiscovery]

Excellent video. It pays to have physics educators all over the world

[@Priya-mp8rs]

Best explanation👍👍👍🙂...only the video which can explain the curved shape of rainbow..

[@mshravanrao8701]

Very nice explanation

[@neutralmind1691]

Thanks for explaining

[@sumukhshenoy]

Very well explained! Thank you 🙏🏻😊

[@saswatsahoo9768]

Superb explanation

[@kashifitifaqbhat571]

This video deserves all the likes on youtube

[@SamM88]

This was the best and easiest explanation!

[@Aa-yk4qe]

Love the explaination

[@AddaOrion]

Best visual explanation I've ever seen. Thank you!

[@saftheartist6137]

Amazing explanation, thank you.

[@sologmr9007]

"If you could get to the end of the 🌈 I can guarantee you a pot of gold"😆

[@littletips6927]

What a great explanation. Thanks ❤😊

[@wangpaul1924]

thanks! so clearly explained

[@mohamedismailmp9655]

Super explanation

[@user-hx5wx2yi3u]

This video was very helpfull for concept of raindow

[@afnansikder3158]

Incredible!!!!

[@mdsaquibansari481]

Excellent

[@ralu4816]

Love it !

[@prasungupta]

Super best explanation

[@worldofscience8703]

Great detaile

[@shihchelin9550]

解釋得非常清楚 我終於知道為什麼彩虹是弧形

[@Antonio-jc3yq]

Por fin, una explicación científica, great great!

[@lilzey_]

Omg literally the best explanation

[@TwinCitiesPBS]

Wow, thanks!

[@AjayKumar-ci9zw]

Very nice...

[@emeraldaisle2927]

The voice of Science Friday!

[@asiangamer5685]

Very interesting

[@ke0nc]

Will they ever get these shows on to DVD?

[@RaviraushanD]

Like, this masterpiece is the master of headmaster itself.💧

[@tiortedrootsky]

Would be cool to learn how to calculate dimentions of the rainbow and distance to it. Distance between red and purple droplets, inner and outer diameter of the whole thing.

[@NorrisSaiyan]

42… the answer to life the universe and everything

[@priyabratadash381]

What they actually missed telling is the existence of Anti solar point about which Rainbow will trace its shape.... else rest of the explanation is fantastic.

[@taecoreing5311]

i wonder now what would happen if i were ascending, what would the rainbow look like if i were still able to see it? i dont think it would dissappear since the curtain of droplets would start from the clouds...?

[@marvinlee7657]

BEST !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@sharan4624]

💥💥

[@discussionwithunathi]

However, I would like to know the length and the height of a rainbow.

[@mohamedismailmp9655]

❤❤❤

[@cool.guy777]

When a rainbow was a rainbow. If you know what I mean

[@Domozorro]

3:33

[@discussionwithunathi]

I have seen a circle rainbow, I think more than 5 times in my life. I have seen while I'm on ground zero

[@TwinCitiesPBS]

Yes! Those are often called Sun Dogs! en.wikipedia.org/wiki/Sun_dog

[@JoseGarcia-rt3fy]

The way it works indoors you need water, light and a mirror. The light needs to shine through the water reflect off the mirror and back on to the water as a rainbow except it won't be curved unless the mirror is curved. If your wondering what that curved mirror is outside its called the FIRMAMENT its in the bible.

[@theredhanded5853]

haha😄 I am happy😁

[@redditsucksyo]

its because of the dome above.

[@zevinbulka3213]

Did somebody say... double rainbow

[@susettemclachlan8765]

A rainbow is curved because it’s a reflection off the dome shaped FIRMament that God stretched over the earth like a tent . Like a prism

[@regalia_usa]

Fantastic vulgarization!

[@stoatystoat174]

:)

[@wardaddy9910]

That doesn't work. You can see the bend of the entire rainbow. The way he explained it you would only see a little portion at a time.

[@rosanna6371]

Nope it doesn’t explain it at all

[@IAlwaysCare]

I still don’t get it.

[@gottogo8675]

Nope . Earth is not a spinning ball and this is not science

[@tarsmoraes6726]

Show your evidences man, explain the midnight sun in Antartica in your plane, explain the 6 months of day and night in North and in the south pole

[@simmzmcnugga9829]

You're right. This is the most ridiculous thing I've ever heard. Light bends in an angular way even WITHIN a raindrop but somehow forms an impossible curve when light only travels in straight lines. Hogwash

[@RawDiscovery]

@@simmzmcnugga9829light is very confusing. You would not believe how complicated any model of light can get. Just because you don’t understand it doesn’t mean it isn’t the truth. Trust me this is very simple compared to other topics like wave-particle duality

[@ashutoshroy2304]

​@@simmzmcnugga9829 the thing is when the light comes to us on a certain angle then only we are able to see the rainbow, only that angle arc is visible to us thats why it appers in this shape
