- 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. The longest wavelengths (around 700 nanometers) are red and the shortest wavelengths (380 nanometers) are violet.

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. This set of colours is abbreviated as VIBGYOR and can be observed easily by passing the sunlight through a gl...
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. The light produced...
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. Fire tends to release heat, smoke, and light as by-products. The light energy produced by the fire can be seen easily by naked eyes; therefore, fire is one of the best examples ...
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. The glow sticks typically consist of two chemical compounds, namely hydrogen peroxide and fluorescent dyes. When the glow stick is present in the rest state, it has a significant am...
Light emission diodes are small electronic components that make use of the conversion and transformation of energy from one form to another. The basic principle of operation of such devices is to use electrical energy as input and release light energy that falls within the visible light range as an output. The application of light-emitting diodes c...
Firecrackers contain a special combination of chemicals that undergo a series of reactions and produce visible light upon being ignited. The conversion of chemical energy to light and sound energy can be observed easily while lighting firecrackers. The light produced by the firecrackers is an example of visible light in real life as it can be seen ...
LASER is an acronym for light amplification by the stimulated emission of radiation. LASER is a device that produces a high intensity, narrow beam of visible light through a process of optical amplification that is based on the stimulated emission of electromagnetic radiations.
A fluorescent lamp is a low-pressure mercury vapour lamp that emits light radiations that fall under the visible range of the electromagnetic spectrum. A fluorescent lamp is also known as a tube light. The main functioning of a tube light is based on the conversion of ultraviolet light into visible light with the help of phosphor coating present on...
Moon does not have its own light, but it reflects the sunlight into the surroundings and therefore, is known as the secondary or reflective source of light. This means that the light reflected by the moon is also an example of visible light in real life.

The most important characteristics of visible light are colour which is both an inherent property of light and an artifact of the human eye. Our eyes include specialized cells known as cones. These cones act as receivers that are tuned to the wavelength of the narrowband of the EM spectrum.

Dec 7, 2022 · In a vacuum, visible light travels at the speed of approximately 299 792 458 metres per second (m/s). This is known as the speed of light. It is the fastest that anything in the universe is able to move! For comparison, the speed of sound is only approximately 300 m/s.
Visible light is a type of electromagnetic (EM) radiation with wavelengths ranging from approximately 380 nanometers (nm) to 750 nm and frequencies between 430 THz and 790 THz. It is situated between ultraviolet (UV) and infrared (IR) radiation in the electromagnetic spectrum.
