How do rainbows form?

- Rainbows are formed when sunlight is scattered from raindrops into the eyes of an observer.
Most raindrops are spherical rather than the often depicted 'teardrop' shape and it is this spherical shape that provides the conditions for a rainbow to be seen. The position of the sun and the raindrops in relation to the observer need to be just right for a rainbow to form: - The sun needs to be behind the viewer - The sun needs to be low in the sky, at an angle of less than 42° above the horizon. The lower the sun in the sky the more of an arc of a rainbow the viewer will see - Rain, fog or some other source of water droplets must be in front of the viewer The size of the raindrops does not directly affect the geometry of a rainbow, but mist or fog tends to disperse the effect more (see fogbows). Rainbows only appear semi-circular over level ground at sunrise or sunset, when the sun is exactly on the horizon, the majority of the time a smaller segment of an arc is seen.

I got the pot of gold! I understood how are rainbows formed.
So, the end of the rainbow is you? and you're the pot of gold. Wholesome
Lol
Flat Earth people swear a rainbow is really a straight line 😂
"And there's no pot of gold" buzz kill
Nice explanation of rainbows to people! Lucky for me you didn't figure out my secret. The fact that you can't ever reach the bottom of a rainbow makes it the perfect place for me to hide my gold 😝
Impeccable video! ALL questions about Rainbows are answered and with very good explanations, so I think it is easy to understand. I was impressed when I once gave water to plants in front of a large glass front of a winder garten and then I saw a rainbow in front of me. So I could create my own rainbow and yes I remember I had the sun in my back.
Awesome video. Please consider making more such videos on different topics of Physics.
Awesome video, the cone shape was all I needed to see
this is the video that I've been searching for years :D
this is the full explanation of a rainbow. Other explanations don't explain the specific angles required, why the arc forms circular, or why we only see the upper part of the arc
mr. MET OFFICE . you are great!!!!!!!!!!!!!!!!!!!! its absolutely fantastic. hope to see more videos
This 4 min animation got my all doubts clear, thank you
I still don't get why you only see one (or two) rainbows when every drop of water (and there would be LOTS of them!) refracts light.
a lot of them do, and they all come together to form an image in your eye. it seems that any of the rays that dont align correctly simply get scattered elsewhere, so you wont see them.
@@AlexWohlbruck but droplets move very fast while rainbow stays the same for an hour. Why?
@@alo2847 I don't really think I understand it either, but here's what I get:
the rainbow that you see is the sunlight that get dispersed from a droplet passed a specific angle (40-42 degrees as in 1:23). as long as it's still raining, then many droplets regularly passed that specific angle, so the rainbow appears to be always there. remember, the droplets have to pass that specific angle otherwise you'll only see it as a white light
just imagine that there's an imaginary section in the sky that if a droplet passes it, then you'll see it as one of the color in the spectrum. highest droplets make red light, lowest droplets make purple light as in 1:37
I hope that make sense.
The Rainbow is water reflecting off of our Firmament.
One guy answered your question with his question..
The reason we see only 1 or 2 is because the we are catching the raindrops with our eyes, at the right angle, at the right time... almost like getting blinded by headlights in the mirror. Only happens at that specific angle..
I got lost in music 😂😂😂😂 I had to rewatch
Amazing.
I got a friend to drive to the end of my rainbow and get my pot of gold.
Perfect explanation! 💙💙
This video was clearly made so that they keep all the gold for themselves!
Thumbs up from me and my physics friend who debated this for hours. (I was right) :)
I followed it to a bank 💀💀💀💀
Thats your pot of gold
but why does violet bend/refract the most and red refracts the least??????
Because of diffrence in thier velocity
because red light has more wavelength so the are slow and something which is slow cannot possibly deviate at a greater wavelength and hence violet deviates more than red. for more clarity watch 0.29 of video. its clear cut.
@@chunksvlogs2097 No! Every colour of white have same velocity. All the colours refract with respect to their wavelength. 👍
Nice explanations 🙏🙏🙏🙏🙏🙏🙏 sir
A rainbow just follows the shape of the sky. Do the experiment using curved glass
Exactly! It is a picture of the Firmament.
Loving the music.

Better than any other explanations.
Watched a couple of rainbow videos which helped me understand this completely. Best description ive found
What this actually confirms is that light bends.
Great explanation, thanks
Excellent! And what's the angle of a secondary arc?
50.4 deg. (red) and 53.4 deg. (violet)
Understandable! Have a great day!
duh, how do you know there is no pot of gold if you've never been there?
The guy has gone really high for this...😃😃Check @2:45....since it is a full circle....there's no end part of rainbow meeting at horizon.....so no pot of gold💰💰😄😄
someone else got there first.
Because the rainbow changes its position as you move but the pot cannot move
So it's simply not there
I already took it. Then how would he find🤐🤐🤐🤐🤐🤐🤐
WHATTT????? There is no pot of Gold at the end of a rainbow?
Don't bother to watch... there's no pot of gold in the end 😅
Very nice animation and explanation
All the info on the Light réfraction and none spent on the motion aspect of the raindrops. The millions of raindrops are all moving at random speed and direction with wind gusts etc. But the rainbow remains steady. Why ?
Because the effect is seen from raindrops at a specific location in the sky. It does not get "carried along" with a falling drop, it gets replaced by the drop that falls into the same(or similar) location an instant later. Much like a movie of an stationary object, where we see then same image in each frame.
No pot of gold?? Oh man
Nice
i hope to see one someday
nice
Amazing explanation,keep up the good work👐
I'm from india🇮🇳🇮🇳🇮🇳🇮🇳
Me too
Clearly understood 👊👊👊
Thanku so much
Tq
What song 🎶 is this ?
wow
Thanks bro, you got me 2marks on exam 👌✌️
👍
Ok
Why don't you speak?😡
I am sicka reading
Anyone from Study School😏😏??
Terrible music tho😢
nice
