- 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 29, 2017 · 1. Photosynthesis for Food formation. The energy from light is trapped as chemical energy and stored as food. As you might have known, this occurs through a process called photosynthesis. Photosynthesis is a concept in biology wherein food is synthesized in green leaves in the presence of light.
Dec 7, 2022 · Waves of Light. 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 · Light from the Sun warms the Earth, drives global weather patterns, and initiates the life-sustaining process of photosynthesis; about 10 22 joules of solar radiant energy reach Earth each day. Light’s interactions with matter have also helped shape the structure of the universe.
Oct 17, 2015 · The fundamentals of light. Electromagnetic (EM) radiation consist of particles called photons, which are colloquially known as “small packets of light”. The main quantifiable properties of EM radiation, or light, are the wavelength, intensity and photon energy.
The cones respond to bright light; other structures called rods respond to dim light, and the pupil regulates the amount of light that enters the eye. The eye responds with maximum sensitivity to light at the middle of the visible color spectrum—specifically, green light with a wavelength of about 555 nm.
Dec 28, 2020 · Science. Physics. Light (Physics): What Is It & How Does It Work? By GAYLE TOWELL Updated Aug 30, 2022. Understanding the particle-wave duality of electromagnetic radiation (light) is fundamental to understanding quantum theory and other phenomena as well as the nature of light.
