Light and its nature have caused a lot of ink to flow during these last decades. Its dual behavior is partly explained by (1)Double-slit experiment of Thomas Young - who represents the photon’s motion as a wave - and also by (2)the Photoelectric effect in which the photon is considered as a particle.

A Revolution: SALEH THEORY solves this ambiguity and this difficulty presenting a three-dimensional trajectory for the photon's motion and a new formula to calculate its energy. More information on 7 months ago.

Properties of the laser beams emitted by the semiconductor lasers (laser diodes or diode lasers) given the broad use of such lasers in low level laser therapy. The basic elements about the laser beam interaction with the tissues are introduced in close connection with the penetration depths of the laser beams into the target. Laser and its Applications. No other scientific discovery of the 20th century has been demonstrated with so many exciting applications as laser acronym for (Light Amplification by Stimulated Emission of Radiation). The basic concepts of laser were first given by an American scientist. Charles Hard Townes. Essentials Of Investments Zvi Bodie Pdf here. Ering the conceptually subtle points of Einsteinian relativity. This basic approach, of reviewing the classical point of view before developing that of modern physics, continues throughout the text, to allow students to build upon what they already know an to develop strong connections be- tween classical and modern physics.
