Question

What is light? Mention it.

Answer 1

Hello friend! Thanks for asking question, here is the answer.

Light is a straight ray of particles which gives brightness to the area where there is a presence of light. It is electromagnetic radiation within a certain portion of the electromagnetic spectrum. Light is a particle as well as a wave. It's a radiation that can be detected by the human eye. Thank you.

Answer 2

hi folk
here is ur answer
in the reality is a bit more complex that what current science is thought in schools.
light us the form of energy which gives us the sensation of visibility in the earth. it was the definition of what is light?
now I will explain what light itself is.
Light is electromagnetic radiation inside a distinctive section of the electromagnetic spectrum. The word most likely refers to seen light , which is noticeable to the human eye.Obvious light is almost always defined as having wavelengths in the range of 400 to 700 nanometres.light transmits spatial and temporal knowledge. This property varieties the basis of the fields of optics and optical communications and a myriad of associated technologies, each mature and rising. Technological purposes centered on the manipulations of light include lasers, holography, and fibre-optic telecommunications systemsIn most day-to-day occasions, the properties of light will also be derived from the speculation of classical electromagnetism, in which gentle is described as coupled electric and magnetic fields propagating through space as a visiting wave. Nevertheless, this wave thought, developed within the mid-19th century, is not sufficient to explain the residences of light at very low intensities. At that degree a quantum thought is required to provide an explanation for the traits of sunshine and to give an explanation for the interactions of light with atoms and molecules. In its simplest type, quantum thought describes light as such as discrete packets of energy, referred to as photons. Nevertheless, neither a classical wave mannequin nor a classical particle mannequin competently describes gentle; light has a twin nature that's printed handiest in quantum mechanics. This surprising wave-particle duality is shared through the entire fundamental ingredients of nature. On account that the mid-twentieth century, a extra complete idea of light, often called quantum electrodynamics (QED), has been regarded with the aid of physicists as whole. QED combines the strategies of classical electromagnetism, quantum mechanics, and the specific thought of relativity.
Albert Einstein developed Planck's theory in 1905 when he studied the photoelectric outcome. First, he started by using shining ultraviolet gentle on the surface of a steel. When he did this, he was capable to become aware of electrons being emitted from the outside. This was Einstein's explanation: If the energy in light comes in bundles, then possible consider of light as containing tiny lumps, or photons. When these photons strike a steel floor, they act like billiard balls, transferring their energy to electrons, which emerge as dislodged from their "guardian" atoms. Once freed, the electrons move along the metallic or get ejected from the outside.
