24 Σεπ 2015 · Light: A Very Short Introduction discusses early attempts to explain light; the opposing particulate and wave theories by scientists such as Isaac Newton and Christiaan Huygens; how light was recognized as an electromagnetic wave in the 19th century; and the 20th-century development of the quantum mechanics view of wave–particle duality.

Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference . Like all electromagnetic waves, light can travel through a vacuum.
15 Δεκ 2021 · One light wave reflects from the outer layer of the soap film that wraps around the air bubble, while a second light wave carries on through the soap, only to reflect off its inner layer. The two light waves travel slightly different distances so they get out of step.
14 Δεκ 2016 · All the studies on light from the antiquity until the middle of nineteenth century were based on incoherent light sources such as the sun, candle light, sodium lamp, or light bulb. In 1950s a new coherent source of light was invented, first in the microwave region and then in the optical region.
20 Νοε 2018 · It explains that the only difference between light, radio waves, and all the other forms of electromagnetic radiation is the length of the fictitious-but-convenient waves or, equivalently, the energy of the photons involved.
14 Δεκ 2016 · A study of optics in the Western and Islamic cultures provides an understanding of the intellectual growth of these societies. This article attempts to retrace this history.
Young and Augustin Jean Fresnel, a French physicist, cooperated in developing the idea that light waves are transverse, that they resemble the waves made when a rope stretched from a post is jerked up and down rather than longitudinal sound waves.
