2012-01-19 · The Institute of Physics produces annual Schools and Colleges' lectures. Prof. Pete Vukusic from the School of Physics at Exeter University delivers the 2007. 2013-01-05 · Sir Isaac Newton's corpuscular theory was one of the earliest scientific attempts at understanding the nature of light. Though it was originally set forward by Pierre Gassendi, it was Newton who had later developed and proposed the 'Corpuscular theory of light. In the early 20th century, we discovered that light is both a particle and a wave. This is called wave-particle duality. But this came as a surprise, because before that we were sure that light was a wave. This previous theory was called the wave theory of light. We has some pretty solid evidence to support the wave theory of light. The Physics Classroom Tutorial presents physics concepts and principles in an easy-to-understand language. Conceptual ideas develop logically and sequentially, ultimately leading into the mathematics of the topics. Each lesson includes informative graphics, occasional animations and videos, and Check Your Understanding sections that allow the. The Physics Hypertextbook is a reaction to the three big problems with textbooks: lack of writer's voice, layouts that reduce readability, and outdated economics. It is a work in progress. Some parts of this book are essentially finished. Some parts are comically underdone. I work on this project in my spare time. You are welcome to use this.

2015-07-18 · “Quantum Theory Made Easy,” a series in which the concepts of quantum physics are broken down for layaudiences in a more digestable manner. More in-depth than most presentations for laypersons, but without the mathematical rigour needed by a specialist in the field. So, you've heard that light. straight lines. This idea that light travels through space along straight lines, although not strictly correct, is the basis of the very useful ray model of light, which explains a great deal about how we see things. The elements of the ray theory, called geometrical optics, will be explored in chapters L2 and L3. A photon is a particle of light defined as a discrete bundle or quantum of electromagnetic or light energy. Photons are always in motion and, in a vacuum a completely empty space, have a constant speed of light to all observers. Photons travel at the vacuum speed of light more commonly just called the speed of light of c = 2.998 x 10 8 m/s.

Physics was known as natural philosophy until the late 18th century. By the 19th century, physics was realised as a discipline distinct from philosophy and the other sciences. Physics, as with the rest of science, relies on philosophy of science and its "scientific. Each theory had valid explanations and justified why light showed certain phenomena. But no one theory could fully explain all the effects of light that were observed, effects such as reflection, refraction, interference, diffraction and the photoelectric effect. Where one theory fell short, the other theory was able to give an explanation.

Light is characterized by several very interesting properties, the observation of which has led to the development of the most prominent theories in contemporary physics – the theory of relativity and quantum mechanics.
