- Light transmits spatial and temporal information. This property forms the basis of the fields of optics and optical communications and a myriad of related technologies, both mature and emerging. Technological applications based on the manipulations of light include lasers, holography, and fibre-optic telecommunications systems.
Dec 7, 2022 · Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength .

- 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.
Nov 14, 2024 · The physicist is interested in the physical properties of light, the artist in an aesthetic appreciation of the visual world. Through the sense of sight, light is a primary tool for perceiving the world and communicating within it.
Oct 17, 2015 · The main quantifiable properties of EM radiation, or light, are the wavelength, intensity and photon energy. The wavelength is used to determine the type of wave involved. Whereas the intensity of light is related to the amount of photons present, which essentially “concentrates” energy.
Mar 3, 2024 · In its simplest form, quantum theory describes light as consisting of discrete packets of energy, called photons. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization.
IIT JEE Study Material. Properties of Light. Light is a form of energy that causes the sensation of vision. Different theories on the nature of light were proposed on the basis of the fact that energy can be transferred from one point to another, either by particle motion or by wave motion.
Dec 28, 2020 · In plain terms, electromagnetic waves are simply known as light, though the term light is sometimes used to specify visible light (that which can be detected by the eye), and other times is used more generally to refer to all forms of electromagnetic radiation.
