... that it doesn’t really matter. When a mirror has shallow curvature, all the reflected rays hit the same point, so 1 could be expressed in any units you like. It could, for instance, be 1 cm, unless your mirror is smaller than 1 cm! The only way to find out anything mathematical about the rays is to ...

... density matrix in monentum space was simulated. This was achieved by using the momentum-space Schrödinger equation for a two-level atom augmented with phenomenological decay terms and solved using the Monte-Carlo Wave Function. The decay constant was taken to be 1/27ns. To obtain pulse shapes and ch ...

For the procedure to be applicable, it has to fulfil two conditions. First, the three-fold patter ...

... The force is deccelerating for negative detuning but is accelerative for positive detuning. Also, for low velocites, the kv terms in the denominator can be neglected towards  0 , thus making the force proportional to the velocity. This is then a true damping force, thus it compresses the velocity ...

Optical coherence tomography (OCT) is an interferometric technique capable of noninvasive high-resolution cross-sectional imaging by measuring the intensity of light reflected from within tissue [1]. Since the technique is non-contact and provides images similar in scale and geometry to histology, i ...

... However, the question “Is light a wave or a particle?” is inappropriate. Sometimes light acts like a wave, and at other times it acts like a particle. Some aspects of the photoelectric effect seemed impossible to reconcile with this wave view of light. For example, the emission of particles from a s ...

Harold Hopkins (physicist)

Harold Horace Hopkins FRS (1918–1994) was a renowned British physicist. His Wave Theory of Aberrations, (published by Oxford University Press 1950), is central to all modern optical design and provides the mathematical analysis which enables the use of computers to create the wealth of high quality lenses available today. In addition to his theoretical work, his many inventions are in daily use throughout the world. These include zoom lenses, coherent fibre-optics and more recently the rod-lens endoscopes which 'opened the door' to modern key-hole surgery. He was the recipient of many of the world's most prestigious awards and was twice nominated for a Nobel Prize. His citation on receiving the Rumford Medal from the Royal Society in 1984 stated: ""In recognition of his many contributions to the theory and design of optical instruments, especially of a wide variety of important new medical instruments which have made a major contribution to clinical diagnosis and surgery.""
