Quantum mechanics is the branch of physics in science that deals with allthe fundamental laws of matter, energy and force at atomic and microscopic levels.It covers all the observations of electromagnetic, mechanical, nuclear,quantum and all other aspects of the physical world. It includes the properties ofenergy and matter and a theory for understanding internal structure of matter, including atoms and molecules. Quantum mechanics describes the behavior of natural systemsby analyzing the motion of matter, energy and information. The key challengein physics and life sciences is to understand how the microscopic properties ofmatter, energy and information reveal their macroscopic properties, the basicproperties of matter and energy being conserved. Quantum mechanics lies at theheart of the modern day mechanical engineering, technological science, physics,chemistry, and molecular biology as well as fundamental developments ininformation technologies and device technology. Quantum mechanical models of electroncsystems are critical to modern materials (inorganic and organic ) physics,chemistry, and technology. Recently, quantum mechanical based theories areused to understand biological (biophysics) systems like brains, eyes, photosynthesis,autism etc.
Electrical engineering involves the study of transfer and distribution ofelectrical power in electronic devices and electronic circuits and is the mainbranch of electrical engineering. There are many different fields of electricalengineering such as circuit design, network analysis, system design, powerelectronics and industrial electronics. This is the engineering sector which dealsconsiderably with electronics and electrical device design. It includes the designof electronic circuits, circuits for computers and control systems, and componentsand materials for other purposes.
1.Definition of quantum mechanical wave: Wave is a disturbance in the motion of someobject from which it may be difficult to recover the original motion. In general,a disturbance in physical property is not necessarily a disturbance in physicalposition of the object. Hence, the disturbance in motion is called wave. d2c66b5586
