Light is a type of energy. It is a form of electromagnetic radiation of a wavelength which can be detected by the human eye. In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not. Light exists in tiny packets called photons. It shows properties of both waves and particles. The study of light, known as optics, is an important research area in modern physics. Five main properties of light are intensity, frequency or wavelength, polarization, phase and orbital angular momentum. In a vacuum (where there is nothing; so, when not slowed down by other particles), light moves at the speed of light; which is 299,792,458 meters, or about 186,282 miles, per second. This means it takes about 8 minutes for light to reach Earth from the sun. In glass it travels at about two-thirds this fast. Light moves in a straight line, creating shadows when the path of light is blocked. More solid things will have a darker shadow, things that are more clear have a lighter shadow, and transparent things will have none or very little shadow. Light can pass through transparent things the most easily. Our eyes react to light; when we see something we see the light it reflects, or the light it emits. For example, a lamp gives off light, and everything else in the same room as the lamp reflects its light.
Every color of light has a different wavelength. The shorter the wavelength, the more energy the light has. The speed at which light moves does not depend on its energy. Going through partly clear objects can slow light down by a very small amount. White light is made up of many different colors of light added together. When white light shines through a prism, it splits up into different colors, becoming a spectrum. The spectrum contains all of the wavelengths of light that we can see. Red light has the longest wavelength, and violet (purple) light has the shortest. Light with a wavelength shorter than violet is called ultraviolet light. X-rays and Gamma rays are also forms of light with even shorter wavelengths than ultraviolet. Light with a wavelength longer than red is called infrared light. Radio waves are a form of electromagnetic radiation with a wavelength even longer than infrared light. The microwaves that are used to heat food in a microwave oven are also a form of electromagnetic radiation . Our eyes cannot see those kinds of energy, but there are some cameras that can see them. The various forms of light, both visible and invisible are the electromagnetic spectrum. When light is refracted in raindrops, a rainbow is made. The raindrop acts like a prism and refracts the light until we can see the colors of the spectrum.
Light as a source of energy is an expression of the existence and life. Light can be defined as that agent, force, or action in nature by the operation of which upon the organs of sight, objects are rendered visible or luminous. Sources of light include the sun, a star, a candle or a lighthouse. Light is the manifestation of the power of perception by vision. Light is a source of energy that makes clear to the mind and soul through spiritual illumination, enlightenment, knowledge, information and creativity. Light is a symbol of prosperity, happiness, joy, felicity, love and remembrance.
