Light

Whatever we see around us is not only as we have eyes, but also due to the presence of light. In order to see anything we need light as it can't be done so in the darkness. Light is the form of energy that is the perfect blend of seven colors to become one as white. For us, the Sun is the chief source of light and heat as well. When a beam of light is passed through a glass prism it disperses into seven different colours. The rainbow we see is the result of this dispersion if the light only. 

One of the most significant properties of life is that it needs no medium to travel. It can also travel in vacuum.
