0:00 today we're going to learn the behind the scenes of something that's absolutely as magical as this what do you think it'll be let me end your Agony and tell you what we're going to learn about how a rainbow is formed so buckle up to this magical episode whether you like the rainy season or not this is one thing no one can ever ever ever ever hit and those are rainbows it feels like the sky is happy when we see a beautiful
0:23 rainbow cross but do you know why a rainbow is formed after it rains I'm sure you'd have thought about it once at least strike so today let me tell you about this amazing process Rainbows are formed when sunlight is scattered into seven colors because the raindrops that act like a prism hmm let's break this down a prism is a long triangular transparent object when sunlight enters this object from one side light bends and we see it gets
0:54 separated into seven colors when it exists from the other side this process is called refraction let me repeat that it's called refraction so sunlight enters a single beam of white color and when it splits into the seven different colors how cool is that now you must be wondering raindrops are not triangular then how do they refract the sunlight that's a good question even the raindrops are not triangular they are transparent and are capable of bending light most raindrops
1:25 are spherical rather than the often defected teardrop shape and it is this spherical shape that provides the conditions for a rainbow to be seen so now you know why we see a rainbow after when it rains sunlight is made up of these seven colors a we can only see it when it is passed through prison-like object now that is some serious business now here are some fun facts about rainbows yeah after a shower rain a rainbow is seen in
1:55 the opposite direction of the sun rainbows actually have no end we might seem to think that they're semicircles are in Arch but they're both circles a rainbow can be properly seen from a plane high above the ground in the 1660s English physicists and mathematician Isaac Newton began a series of experiments with sunlight in prison it was he who showed that clear white light was made up of seven colors out of all of Hawaii's islands KO e stands out as
2:26 the place with most Rainbows are seen needless to say it rains a lot on that island however the number of rainbows that result is the reason Hawaii is known as the rainbow State now Rainbows are extremely popular but have you ever heard about a moonbow it is an optical event caused when the light from the Moon is refracted through water droplets in the air now trust me I did not know this fact but the amount of light
2:52 available even from the biggest and brightest full moon is far less than what is produced by the Sun so moonbows are incredibly faint and that is they're not very visible and so very rarely see now how sad is that would you like to see a moon boat too I don't know about the moon but I have an experiment that can help you make rainbows even when it doesn't rain until a water spray can which we can use
3:17 to water the plants and go out and stand in the direction of the sun this means your back must be facing the sun now spray your water in front of you and there you go you should be able to see your very own rainbow now it won't be as big and bright but it is very pretty for sure a pan summer experiment you must try yeah okay now it's quiz time so let me ask you this one who showed that
3:41 light is made up of seven colors Isaac Newton does a rainbow have a starter in it no its Rainbows are usually round what is a rainbow caused by Moonlight wall a moonbow where it is a rainbow Walker in the opposite direction of the sun which place is called the rainbow state Hawaii what do raindrops act as for a rainbow to be formed a prism that is correct you're all very smart kids now wasn't this an interesting topic
4:11 share this with your friends and family and do try out this good experiment foreign [Music]
Summary
- Rainbows are created when sunlight is refracted through raindrops, which act as prisms.
- The process of light bending and splitting into colors is called refraction.
- Raindrops are typically spherical, which allows for the formation of rainbows.
- Rainbows appear opposite the sun and are actually full circles, not just arcs.
- Isaac Newton demonstrated that white light is made up of seven colors through experiments in the 1660s.
- Hawaii is known as the "Rainbow State" due to its frequent rainbows, particularly on the island of Kauai.
- Moonbows are faint rainbows created by moonlight refracting through water droplets, but they are rarely seen.
- An experiment to create a rainbow involves spraying water in front of you while facing away from the sun.
