Why Is A Rainbow Curved? | Newton's Apple
Вставка
- Опубліковано 13 лют 2022
- 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.

This is the best explanation I've seen! Thank you!
So the sun is a laserpointer?
definitely not
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.
Same here! I just watched a bunch of videos, and started to get it, but this one put it all together! Funny how an older video can be so much better! Loved all the models!
Excellent video. It pays to have physics educators all over the world
2:38 the Carl Sagan impression was spot on lmao
This video deserves all the likes on youtube
Best explanation👍👍👍🙂...only the video which can explain the curved shape of rainbow..
Very nice explanation
Superb explanation
This was the best and easiest explanation!
Thanks for explaining
Very well explained! Thank you 🙏🏻😊
Love the explaination
This is cool, so cool.
Amazing explanation, thank you.
What a great explanation. Thanks ❤😊
"If you could get to the end of the 🌈 I can guarantee you a pot of gold"😆
Incredible!!!!
Love it !
thanks! so clearly explained
This video was very helpfull for concept of raindow
Super explanation
Excellent
Super best explanation
Best visual explanation I've ever seen. Thank you!
Omg literally the best explanation
Wow, thanks!
Great detaile
解釋得非常清楚 我終於知道為什麼彩虹是弧形
Very nice...
Very interesting
The voice of Science Friday!
Por fin, una explicación científica, great great!
Like, this masterpiece is the master of headmaster itself.💧
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.
BEST !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
💥💥
Will they ever get these shows on to DVD?
This was so good, and I grew up watching PBS, but don't know this show!
@@richardmahn7589 Technically it wasn't a PBS show and was not on the schedule. It's possible your station didn't carry it. The PBS stations who chose to buy it, usually aired it non-primetime on weekends.
Can somene who knows tell me what year this particular episode was broadcasted? Late 80s?
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.
❤❤❤
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...?
When a rainbow was a rainbow. If you know what I mean
42… the answer to life the universe and everything
haha😄 I am happy😁
3:33
However, I would like to know the length and the height of a rainbow.
It all depends where the raindrops are, and where you are, and the angle of the sun light. You are the focal point.
I have seen a circle rainbow, I think more than 5 times in my life. I have seen while I'm on ground zero
Yes! Those are often called Sun Dogs! en.wikipedia.org/wiki/Sun_dog
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.
its because of the dome above.
Did somebody say... double rainbow
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
:)
Nope it doesn’t explain it at all
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.
Fantastic vulgarization!
I still don’t get it.
Bahahaha people are actually believing!!😂 🧢
Nope . Earth is not a spinning ball and this is not science
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
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
@@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
@@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
Nature is WOKE 😡
