After introducing the physical parameterization of light in terms of standard units, three concepts of light are introduced: light as a wave, light as a quantum particle, and light as a quantum field.
21 Οκτ 2024 · Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 metres to radio waves measured in metres.
A BRIEF HISTORY OF LIGHT, AND THOSE THAT LIT THE WAY is a summer's day roller-coaster ride through five centuries of man's achievements in understanding and manipulating light. Contents: 16th and 17th Centuries
14 Δεκ 2016 · We have come a long way from the earliest studies on light, trying to understand vision as light emanating from our eyes, to the description of light as rays, then as particles, and then waves, and finally exhibiting both particle and wave natures.
21 Οκτ 2024 · In his Traité de la Lumière (1690; “Treatise on Light”), the Dutch mathematician-astronomer Christiaan Huygens formulated the first detailed wave theory of light, in the context of which he was also able to derive the laws of reflection and refraction.
20 Νοε 2018 · ‘Electromagnetic waves’ considers the history of the scientific investigation into the electromagnetic spectrum, including Einstein’s insight into the quantized nature of electromagnetic radiation.
The author, writing for an audience of both students and other scientifically interested readers, describes fundamental investigations of the nature of light and ongoing methods to measure its speed as well as the emergence of the wave theory of light and the complementary photon theory.
