Abstract This paper deals with the discussion of mass and energy in light. Light consist of very less amount of mass that it could not be measured. This paper is based on the concept that when the mass of light is increased it can move the objects. So, the light with increased mass can be used in many applications in practical life such as producing electricity. Increase of mass in light, leads to much more attraction in the academic sphere. It is necessary to take the broad view of this information. This paper focuses on these issues. Keywords: mass, energy, light. Introduction This paper aims to discusses the mass and energy in light, Light consist of very less amount of mass, so we are going to increase the mass then the light will be able to move the object, so that the light is used to produce electricity. Thus light is used to reduce more works in practical life. Light is used for many applications. Increase of mass in light, leads to much more attraction in the academic sphere. It is necessary to take the broad view of this information.

Objectives Objective is we are going to increase the mass in light.

LIGHT Light or visible light is the portion of electromagnetic radiation that is visible to the human eye, responsible for the sense of sight. Visible light has a wavelength in a range from about 380 or 400 nanometres to about 760 or 780 nm,[1] with a frequency range of about 405 THz to 790 THz. In physics, the term light often comprises the adjacent radiation regions of infrared (at lower

frequencies) and ultraviolet (at higher), not visible to the human eye. [2][3] Primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization, while its speed, about 300,000,000 meters per second (300,000 kilometres per second) in vacuum, is one of the fundamental constants of nature. Light, which is emitted and absorbed in tiny "packets" called photons, exhibits properties of both waves and particles, this property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.

PHOTON In physics, a photon is an elementary particle, the quantum of the electromagnetic interaction and the basic unit of light and all other forms of electromagnetic radiation. It is also the force carrier for the electromagnetic force. The effects of this force are easily observable at both the microscopic and macroscopic level, because the photon has no rest mass; this allows for interactions at long distances. Like all elementary particles, photons are currently best explained by quantum mechanics and will exhibit wave–particle duality, exhibiting properties of both waves and particles. For example, a single photon may be refracted by a lens or exhibit wave interference with itself, but also act as a particle giving a definite result when quantitative momentum (quantized angular momentum) is measured. The modern concept of the photon was developed gradually by Albert Einstein to explain experimental observations that did not fit the classical wave model of light. In particular, the photon model accounted for the frequency dependence of light's energy, and explained the ability of matter and radiation to be in thermal equilibrium. It also accounted for anomalous observations, including the properties of black body radiation, that other physicists, most notably Max Planck, had sought to explain using semi classical models, in which light is still described by Maxwell's equations, but the material objects that emit and absorb light are quantized. Although these semi classical models contributed to the development of quantum mechanics, further experiments validated Einstein's hypothesis that light itself is quantized; the quanta of light are photons. In the Standard Model of particle physics,...
