Webrainbow: [noun] an arc or circle that exhibits in concentric bands the colors of the spectrum and that is formed opposite the sun by the refraction and reflection of the sun's rays in raindrops, spray, or mist. Web1. Light from sun strikes raindrop. White light from the Sun has to hit the raindrops at a certain angle before a rainbow is possible. It is best if the sun is fairly low in the sky such as dawn and late afternoon. The angle is important as it effect the direct the light travels after it hits the raindrops and that determines whether or not we will see a rainbow.

WebThe refractive index of water is 1.33 whereas the refractive index of air is 1.00029. Thus, to understand the concept of Snell’s Law let’s consider the light of wavelength 600 nm that goes from water into the air. To calculate the angle made by the outgoing ray we apply the figures in the formula mentioned above. 1.33 sin 30o = 1.00029 sin x.

WebRainbows: Refraction of the Seven Colors of the Spectrum. A rainbow has seven colors because water droplets in the atmosphere break sunlight into seven colors. A prism similarly divides light into seven colors. When light leaves one medium and enters another, the light changes its propagation direction and bends. This is called refraction.
