- In addition to being a particle, light also behaves like a wave, and when people talk about light, what they're mostly referring to is visible light, which is only a fraction of the whole electromagnetic spectrum – most of which we can't see with our eyes.

Aug 10, 2016 · The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.

Visible light is a type of electromagnetic radiation, which is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic spectrum. That spectrum is typically divided into seven regions in order of decreasing wavelength and increasing energy and frequency. These region...
Perhaps the most important characteristic of visible light is color. Color is both an inherent property of light and an artifact of the cells in the human eye. Objects don't "have" color, according to The Physics Hypertextbook. Rather, they give off light that "appears" to be a color. In other words, Elert writes, color exists only in the mind of t...
As objects grow hotter, they radiate energy dominated by shorter wavelengths, which we perceive as changing colors, according to NASA's Mission Science. For example, the flame of a blowtorch changes from reddish to blue as it is adjusted to burn hotter. This process of turning heat energy into light energy is called incandescence, according to the ...
The color of hot objects, such as stars, can be used to estimate their temperatures, according to IDEA. For example, the sun's surface temperature is about 5,800 kelvin (9,980 F or 5,527 C). The light emitted has a peak wavelength of about 550 nm, which we perceive as visible white light (or slightly yellowish). According to NASA, if the sun's surf...

- Sunlight. The light that we receive from the sun is a prominent example of visible light in real life. The sunlight appears to be white in colour, but contains a set of seven colours arranged in a specific order according to the value of wavelengths.
- Light Bulb. An electric light bulb is a common light source used in households. It consists of a filament made up of tungsten. When the switch is connected and a closed circuit is formed, the electric current passing through the filament of the electric bulb tends to increase the temperature to a level after which it begins to produce light.
- Fire. Fire is produced as a result of the combustion of combustible elements. It is a chemical process that is highly exothermic in nature and causes rapid oxidation of the fuel.
- Glow Sticks. The light that is radiated by the glow sticks into the environment can be seen easily by naked eyes and therefore, is yet another example of visible light in real life.
Oct 19, 2023 · Visible light waves are the only wavelengths of the electromagnetic spectrum that humans can see. The different wavelengths of visible light are seen as the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.
Jan 16, 2021 · The visible light spectrum is the region of the electromagnetic spectrum that human eyes see. It runs from wavelength of about 400 nanometers (nm) at the violet end of the spectrum to around 700 nm at the red end of the spectrum.
