to aerials. Microwaves are detected with piezoelectric crystals. Visible light is detected by photoelectric cells. 4. explain that the relationship between the intensity of electromagnetic radiation and distance from a source is an example of the inverse square law: I d12 Electromagnetic radiation attenuates over distance‚ i.e. the further you are away from an electromagnetic source the less the intensity will be. This can be applied to light‚ as if you move away from a light it will be less

Professionalism is an adherence to a set of values comprising both a formally agreed-upon code of conduct and the informal expectations of colleagues‚ clients and society. The key values include acting in a patient’s interest‚ responsiveness to the health needs of society‚ maintaining the highest standards of excellence in the practice of medicine and in the generation and dissemination of knowledge. In addition to medical knowledge and skills‚ medical professionals should present psychosocial and

by losing atomic particles (protons‚ neutrons‚ or electrons). When solid radium decays to form radon gas‚ it loses two protons and two neutrons. These two protons and two neutrons are called an alpha particle‚ which is a type of radiation. The elements that produce radiation are called radioactive.

of electromagnetic radiation with matter in the experiment it means it’s the usage of ultra-light to measure the absorbance of the copper sulpate. The regions of the electromagnetic spectrum immediately adjacent to the high- and low- energy extremes of the visible region are known as the ultraviolet (UV) and infrared (IR) regions respectively. Thus a quantum of UV radiation possesses more energy than one in the visible region whilst the reverse is true for quantum of IR radiation. All spectrophotometric

comes from atoms that are in a excited state because of the high thermal energy of the flame. Each element is measured by absorption or emission of ultraviolet or visible radiation by the gaseous atoms. Samples are vaporized between 2000 and 8000 K and the vapors are measured by absorption of characteristic wavelengths of radiation. The samples should be diluted to ppm to analyze major constituents. Chemical equations that were used were the equation of the line y = mx + b which would be attained

SPECTROPHOTOMETRY Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength It involves with the use of a spectrophotometer. A spectrophotometer is a photometer that can measure intensity as a function of the light source wavelength. A spectrophotometer is commonly used for the measurement of transmittance or reflectance of solutions‚ transparent or opaque solids‚ such as polished glass‚ or gases. Principles

The Military’s Pandora’s Box by Dr. Nick Begich and Jeane Manning This article was prepared to provide a summary of the contents of a book written in 1995 which describes an entirely new class of weapons. The weapons and their effects are described in the following pages. The United States Navy and Air Force have joined with the University of Alaska‚ Fairbanks‚ to build a prototype for a ground based "Star Wars" weapon system located in the remote bush country of Alaska.

ABSTRACT The short and unpredictable nature of the conventional chemical batteries‚ along with the frequent replacements that they require‚ has created an acute need for a reliable‚ longer-lasting and rugged source of energy. Moreover Radars‚ spacecrafts‚ interstellar probes and other advanced communication devices require much larger power than that can be met by conventional energy sources. The solution to long term energy source is the nuclear powered batteries which have a life span of few
