Rainbow is one of the most beautiful scenery that nature has to offer – its beautiful, Rainbow has inspired many fairy tales, songs, and legends. We may be willing to bet that most of the artists behind the fairy tale don’t really know the phenomenon of the rainbow – like most people today.
But science about the process of this rainbow is actually very simple. This is a basic optical science. In this article, we will know how rain and sun are aligned to create color in the sky.
- Light Bending
The basic process of Rainbow is refrfitting. Light is bent – or rather, a change of direction – when traveling from one medium to another. This happens because the light moves at different speeds on different mediums.
To understand why light turns, imagine you’re pushing the shopping cart in the parking lot. The parking lot is one of the “media” for your shopping cart. If you exert constant force (power), the speed of the shopping cart depends on the surface of the media traversed – in this case, the surface is paved in the parking area.
What happens when you push the shopping cart from a parking spot to a grass area? Grass is a different “medium” for shopping cart. If you push the basket directly into the lawn, the rate of the basket slows down. Grass Media gives more resistance, so it takes more energy to move the shopping cart.
But when you push the basket to the lawn area at the corner, the thing that happens will be different. If the right wheel touches the grass the first time, the right wheel slows down as the left wheel is still on the asphalt road. Since the left wheel moves briefly faster than the right wheel, the shopping cart will turn right when moving to the grass. Similarly, otherwise, if you move at an angle from a grass area headed into a paved area, one wheel will move faster before the other wheel and the direction of the cart will change.
Causes of Rainbows
Rainbows are natural phenomena that occur when sunlight and rain react with each other in a certain way. This phenomenon of natural phenomena is very interesting because it forms a beautiful color that is aligned and curved in the sky and other medium. The rainbow can only be seen when there is sunlight, the right sun angle, and the spatters. Sunlight serves as a source of light that is refract by a rainwater prism. Therefore, without sunlight there will never be a rainbow. This is what causes at night we can not see the rainbow.
- Rainbows are formed when light passes through small droplets of water in the air. Light is reflected and refracted by the water droplets. Sunlight looks white, but it actually consists of a combination of many colors.
- Each color is refracted differently. So, each raindrops spreading the white color of sunlight into the colors of the components of red, orange, yellow, green, blue, Indigo, and Purple (Mejikuhibiniu).
- The red light turns at a relatively low angle and when it enters the raindrops, while the purple light Benps at a relative sharpest angle. We see only one color of each raindrop
- When a higher water droplet disperses the light, the red light exits at the right angle to move towards the observer’s eye. The other colors turn outside at a lower angle, so the observer does not see it.
- From the lowest raindrops, the light purple comes out at the right angle to move towards the observer’s eyes. The raindrops that are between the top and bottom reflect the different shades of light to the observer, allowing the observer to see the full spectrum of colors.
