White light is created by combining all colors of the visible light spectrum. It is emitted by sources such as the sun, incandescent bulbs, and fluorescent lamps. White light is part of the electromagnetic spectrum, and filtering it gives objects their colors. Some holistic healers believe white light stores positive energy and can purify and protect auras.
White light is the name given to what the human eye sees when all the colors that make up the spectrum of visible light are combined; the visible light spectrum is made up of red, orange, yellow, green, blue, indigo, and violet light, and these colors combined create white lighting. When shining through a prism, white lights are broken up into the separate colors of the visible light spectrum. Many people commonly refer to white light simply as “light” or “visible light,” and it is this light that makes it possible to see your surroundings. There are several sources of white light including the sun and stars, some types of light bulbs, and some lamps.
sources
Incandescence, which is visible light created by heat, is the largest known generator of white light. Objects with cooler temperatures emit infrared radiation, which can’t be seen, but as an object gets hotter, the wavelengths get shorter and brighter, going from red to yellow to white; these white lights are visible to the human eye. In addition to the sun and the ordinary light bulb, molten materials such as metal or glass also glow incandescently.
Most light sources are thermal, which means that the type of radiation they emit is a characteristic of the temperature of the source. Visible light is mainly radiated by the sun and many other stars. In fact, most of the energy radiated by the sun is within the visible spectrum, which is why humans can see this range of light. Other sources of white light include incandescent bulbs, fluorescent lamps, halogen lamps, white LEDs and flames.
electromagnetic spectrum
White light waves are part of the electromagnetic (EM) spectrum, which also includes radio waves, microwaves, infrared, ultraviolet, X-rays and gamma rays. The only part of the EM spectrum that the human eye can see without the use of technology is the visible white light band. This spectrum is huge, with waves that vary considerably in magnitude; there are waves thousands of miles (kilometers) long, waves smaller than atoms, and everything in between. Visible light exists in a very narrow band of the electromagnetic spectrum, between infrared (IR) and ultraviolet (UV).
It is the filtering of white light that gives color to objects. The sky on Earth is blue because air molecules filter out most of the wavelengths of red light from the white light that comes from the sun. Objects absorb and reflect different light waves to produce all visible colors.
Alternative definition
While a less common definition of the term, some holistic healers refer to white light as a part of the universe that stores all positive energy. By calling in white light, it is believed that auras can be purified and protected from negative energy. Spiritual healers, yogis, and mystics are among those who attempt to connect with this light, often through prayer and meditation.
