Why do Rainbows Arc?
Rainbows are definitely a wonder to the sky and a delight to the eyes. Rainbows are typically formed when droplets of moisture in the Earth’s atmosphere are struck by the rays of Sun. When such thing happens in a timely instance, a spectrum of colors is produced, harbouring the sky with colors that are famously abbreviated as ROYGBIV. While this fact has become the concern of most of the general population, some critical individuals find in depth interest in how they are able to form an arc in the sky.
Colorful as they are, rainbows basically take the form of an arc. Such form is basically due to one predominantly existing fact that light is able to refract. The concept of refraction is perceived in the light’s ability to bend in a series of angles when the substances involved has the capacity to let light bounce back. As in the case of rainbows, they are produced basically because droplets of moisture in the atmosphere allow the sun’s rays to be bent. When the sun’s rays are bent, it is produced into angles that possess different colors.
Along with these colors are the elements of wavelengths that are also one of the reasons why rainbows obtain the arc form. The variation of wavelengths that colors possess contributes to their ability to bend the light rays being projected. Colors having shorter wavelengths have lesser ability to refract while those having linger wavelengths tend to be bent at a farther distance.
While it seems that rainbows are entailed with complexities, rainbows remain to be one of the most appealing sites to see. They are indeed, an apple to the naked eye. Furthermore, they have become one most useful sources of inspiration and amusement for both men and women alike.
