Physics Of Rainbows

Whenever we look at the rainbow, we stand in awe and wonder how it is possible for so many colors to appear in the same shape and in the same order. Well, all this is based on the laws of dispersion of physics, and also the way light behaves. It is one of nature’s wonders also. There are two phenomena of physics at work while creating a rainbow. One is reflection of light, and the other is refraction of light.

Refraction is a phenomenon that occurs whenever light passes from one medium to another such as air to water for example. Whenever light passes from one medium to another, it bends at various point and angles, depending on the wave length of the light. When a single ray of sunlight falls or passes through a droplet of water, the white band of light gets broken into various spectrums of colors.

Reflection is the phenomenon that occurs after refraction. After the white light breaks and disperses, the water droplets carry the light and form various bands of color resulting in a beautiful rainbow. This simple experiment can be performed at home also using a light bulb and water droplets. You can also use a prism to observe the dispersion of light into colors. However, during reflection process, most of these lights come together again.

Understanding a rainbow is a simple task and also an interesting one. When light enters raindrops, it disperses in different directions causing various bands of colors and resulting in a rainbow. A rainbow mainly occurs when there is rain and also when the sun is shining.

Physics Of Sunsets

Physics-Of-Sunsets      The sun emits several types of rays of light and they all differ in frequencies. Some of these rays are visible to the human eye, and these falls under the visible light frequencies. Most of the visible light frequencies are white in color. The white light is mainly responsible for lighting up the earth. The light that reaches the earth are of different frequencies. More..
