Quantum mechanics

With the arrival of quantum mechanics in the early decades of the 20th century, however, the controversy over the nature of light resurfaced. As will be seen in the following sections, this scientific conflict between particle and wave models of light permeates the history of the subject.

20th Century

Pythagoras of Samos (580-495 B.C.) and Leucippus (460-370 B.C., approx.) argued that light was "something" that flows and is captured by our eyes, exciting the sense of sight; This interpretation was called the "emission theory" or "intrusion theory." Plato (427-347 B.C.) complicates the Pythagoras theory, assuming an action between something that emanates from three points: the eyes, the object that is seen and that which produces the illumination.

Some ancient Greek philosophers, among them Empedocles (495-435 BC, approx.), considered light as a fluid that emanated from the eyes of the observer, which acted like tentacles, resembling the sense of sight to the eye. sense of touch. This interpretation of the nature of light was called the "tactile theory" or "extramission theory."

Egypt, where metallic bronze or copper mirrors were created (2900 BC) for aesthetic purposes. The manipulation of glass, also in Egypt, is another relevant activity to consider within the evolution of light theories and developments in optics; According to archaeological studies, it was after the use of metallic mirrors (1500 BC).

EMpedocles y Aristoteles

Theoretical and experimental work in the mid to late 19th century convincingly established light as an electromagnetic wave, and the issue seemed to be resolved by 1900.

This experiment played a major role in the general acceptance of the wave theory of light.[1] In Young's own judgement, this was the most important of his many achievements.

In modern physics, the double-slit experiment demonstrates that light and matter can satisfy the seemingly-incongruous classical definitions for both waves and particles.

Newton’s corpuscular model survived into the early years of the 19th century, at which time evidence for the wave nature of light became overwhelming.

Thomas Young

Thomas Young was a British polymath who made significant contributions to the fields of vision, lightHe was born on June 13, 1773, in Milverton, Somerset, England, and died on May 10, 1829, in London. Young was a physician and physicist who established the principle of interference of light and resurrected the century-old wave theory of light.

Quantum Mechanics

Science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.

The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.

Experiment

Issac Newton

The creation of the rainbow

In 1666, Newton observed that the spectrum of colours exiting a prism in the position of minimum deviation is oblong, even when the light ray entering the prism is circular, which is to say, the prism refracts different colours by different angles. During this period he investigated the refraction of light, demonstrating that the multicoloured image produced by a prism, which he named a spectrum, could be recomposed into white light by a lens and a second prism.

Was a Scottish physicist with broad interests and scientist responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the "second great unification in physics" where the first one had been realised by Isaac Newton.

NANOPHOTONICS

A LITTLE WORLD OF THE LIGHT

Nanophotonics or nano-optics is the study of the behavior of light on the nanometer scale, and of the interaction of nanometer-scale objects with light. It is a branch of optics, optical engineering, electrical engineering, and nanotechnology. It often involves dielectric structures such as nanoantennas, or metallic components, which can transport and focus light via surface plasmon polaritons.
