What is white light? (with photos)

Fluorescent lamps emit white light.

White light is the name given to what the human eye sees when all the colors that make up the visible light spectrum are combined; The visible light spectrum is composed of red, orange, yellow, green, blue, indigo, and violet light, and these colors combine to form white light. When illuminated by a prism, white lights are split into separate colors of the visible light spectrum. Many people often refer to white light simply as “light” or “visible light”, and it is this light that makes it possible to see the surroundings. There are several sources of white light, including the sun and stars, certain types of lamps, and some lamps.


When the entire visible spectrum is combined, the result is white light.

Incandescence, which is visible light created from heat, is the largest known generator of white light. Objects with lower temperatures emit infrared radiation, which cannot be seen, but as an object gets hotter, the wavelengths get shorter and brighter, moving 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.

For some holistic healers, white light can cleanse and protect auras from negative energy.

Most light sources are thermal, which means that the type of radiation they emit is a characteristic of the source’s temperature. 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 likely why humans can see this range of light. Other sources of white light include incandescent lamps, fluorescent lamps, halogen lamps, white LEDs and flames.

electromagnetic spectrum

Spiritual healers try to connect with the white light through prayer and meditation.

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 range. This spectrum is huge, with waves that vary considerably in size; there are waves thousands of miles (kilometers) in length, 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 much of the wavelengths of red light from the white light that comes from the sun. Objects absorb and reflect different waves of light to produce all the colors that can be seen.

Alternative Definition

Although it is 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 invoking white light, it is believed that auras can be cleansed and protected from negative energy. Spiritual healers, yogis and mystics are among those who try to connect with this light, often through prayer and meditation.
