The primary and secondary rainbows are the two types of rainbows. It is not uncommon to witness two rainbows after a rainstorm. It should be pouring on the side of the sky opposite the sun.A portion of the sky should be illuminated by the sun.Two requirements must be met for a rainbow to appear: A rainbow is formed when sunlight passes through water droplets in the atmosphere and is reflected and refracted. As a result, clouds are usually white.ĭo you want to know the name that comes under some natural phenomena that occur due to the sunlight? Well, it is a Rainbow!Ī rainbow is the most beautiful optical phenomenon that occurs in the sky. The scattering takes place as per Rayleigh scattering (The amount of scattering is inversely proportional to the fourth power of the wavelength).Īlthough indeed, all wavelengths are almost equally scattered for big scattering items, such as a raindrop, dust, or ice particles, this is not true for small scattering objects like a raindrop, dust or ice particles. Water and dust are two examples of big particles found in the atmosphere. This is the reason why the sky looks blue. As a result, the blue color scatters the most, and the small atmospheric particles spread it in all directions. Blue is the color with the shortest wavelength in the white light spectrum. The atmospheric particles disperse sunlight as it enters the Earth’s atmosphere. Have you ever wondered why it appears to be blue? It is common to describe the sky as blue. Light with shorter wavelengths scatters significantly more than light with longer wavelengths. Scattering of light is a phenomenon in which the path of light impacting a particle is deflected in a different direction. This is because light scatters by minute particles of air in the laser beam’s passage. However, one can observe the path with the help of the laser beam. We can’t perceive the passage of light when we enter a dark room. Here are a few examples of some natural phenomenons due to sunlight: Light is electromagnetic radiation that, when it penetrates the Earth’s atmosphere, causes many phenomena such as the formation of rainbows, blue skies, reddish sunsets and white cloud formation. A light usually goes through multiple processes that include refraction, reflection, dispersion and diffraction. We understand that light is one of the most essential types of energy that is responsible for a wide range of natural events. Why does Sunlight Affect Natural Phenomena? These natural occurrences will have no adverse effects on the ecosystem. Some natural phenomena that occur due to the sunlight include the breeze, rain and a sunny day. Do you know why the sky appears blue and the clouds appear white? All of this is attributable to the sun. You might have noticed the blue coloured sky, white clouds and crimson sky.
