Boundary conditions for electric and magnetic fields |
|
Answer» The differential forms of Maxwell's equations are used to solve for the field vectors provided the field quantities are SINGLE valued, bounded and continuous. At the media boundaries, the field vectors are discontinuous and their behaviors ACROSS the boundaries are governed by boundary conditions. The integral equations(eqn 5.26) are assumed to hold for regions containing discontinuous media.Boundary conditions can be derived by applying the Maxwell's equations in the integral form to small regions at the interface of the TWO media. The procedure is similar to those used for obtaining boundary conditions for static electric fields (chapter 2) and static magnetic fields (chapter 4). The boundary conditions are summarized as FOLLOWS |

Any difference between spectrometer and spectroscopy |
|
Answer» Spectrometry is a generic name for determining the nature of a substance by quantifying some observable PROPERTY, such as EMITTED light, the rate at which ions MOVE through a medium, or backscattering of ions fired at a material, into finely divided bins. Together, the bins form a sort of signature that identifies the composition of a substance. Spectrography is a TYPE of spectrometry that sorts electromagnetic radiation into a series of bins based on the wavelength of the photons of radiation. When heated, all atoms emits such radiation, not only in the visible part of the spectrum but throughout the spectrum. A spectrograph can be used to identify the atoms and molecules present in an unknown sample, or to determine the composition, DISTANCE, and approximate temperature of objects in space. |

Newton's laws of motion defined along with formulas |
|
Answer» First Law of MOTION states that a body at rest will remain at rest UNLESS an outside FORCE acts on it, and a body in motion at a constant velocity will remain in motion in a straight line unless acted UPON by an outside force. experienced by an object is directly proportional to the net force (Fnet) experienced by the object and inversely proportional to the mass of the object. ... The a = Fnet/m equation can be used as both a formula for problem solving and as a guide to thinking. hope this helps |
