🐆 How Rainbow Is Formed Class 10
Rainbows are created when the sun is scattered by water driblets ( similar to drops or fog) in a process known as refraction. When the sun passes through a medium-thick than air, similar to a droplet, it refracts, changing its direction.A rainbow is a multicolored arc, or curved line, in the sky. Most rainbows form when the sun's rays strike raindrops falling from faraway rain clouds. Rainbows appear in the part of the sky opposite the sun, usually in the early morning or late afternoon. From inside to outside, the colors of a rainbow are violet, indigo, blue, green, yellow,
A rainbow is a natural spectrum of sunlight in the form of bows appearing in the sky when the sun shines on rain drops. It is combined result of reflection, refraction and dispersion of sunlight from water droplets, in atmosphere. Always it formed in the direction opposite to the sun.
Rainbow Formation. Dispersion of Light by Prisms. Rainbow Formation. Mirages. One of nature's most splendid masterpieces is the rainbow. A rainbow is an excellent demonstration of the dispersion of light and one more piece of evidence that visible light is composed of a spectrum of wavelengths, each associated with a distinct color.
Rainbows are formed when light from the sun is scattered by water droplets (e.g. raindrops or fog) through a process called refraction. Refraction occurs when the light from the sun changes direction when passing through a medium denser than air, such as a raindrop. It forms due to refraction, reflection, and dispersion of sunshine in water droplets resulting in a spectrum of sunshine appearing within the sky. It is seen as a beautiful multicoloured circular arc in the sky. Rainbows are often full circles. However, practically an observer usually sees only an arc formed by illuminated droplets above rock .
