- Light is electromagnetic radiation that can be detected by the eye. Light is therefore a form of radiant energy. Light is essential to life. For example, plants feed partly on sunlight through the process of photosynthesis. The energy carried by light also helps to warm the Earth, creating the right climate for the development of life.

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.
Dec 29, 2017 · Light is widely used to study the properties of radiation. It is also used to study its properties and interaction with matter as a part of optical physics. Light is also essential to observe objects in the universe for the Astronomers.
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.
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.
Light has seven main properties. 1. Light is electromagnetic radiation that can be perceived by the eye. Other electromagnetic radiation, such as x-rays or infrared rays, are not detected by our eyes.
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.
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.
