Rainbow phenomenon
Whether it is a child or an adult, the person must be excited to see the rainbow. Most will stop for a moment and look up to the sky to enjoy this beautiful nature phenomenon.
Have we wondered why the shape of the rainbow is always semi circle? And you know that actually the rainbow does not even exist? Yes, the rainbow does not exist. When sunlight beams through water droplets, it is refracted or it is bent. Then, it is reflected on the surface of the droplet and refracted again to get out of the droplet. The electromagnetic spectrum consists of light with different wavelengths. So, the spectrum is spread out and forms a rainbow. So, what exactly is a rainbow? It's just an optical illusion when viewed from an angle of 42° by turning your back on the sun. It all depends on our point of view. If two people see the same rainbow, each will get different views based on the angle from which they see it.
