1.0 INTRODUCTION Flame photometry‚ also referred to as ’flame atomic emission spectrometry ’ is a quick‚ economical and simple way of detecting traces of metal ions‚ primarily Sodium‚ Potassium‚ Lithium‚ Calcium‚ and Barium‚ in a concentrated solution. The process is an extension of the principles used in a flame test‚ with the main differences having more precision in the results‚ and the use of more advanced technology. This report focuses on the theory‚ applications‚ limitations and analysis

The electron microscope‚ instrument that produced the first magnified image showing three-dimensional’ and highly magnified image of a small object. It directs a beam of electrons rather than light through a specimen. The beam of electrons is created from an electron gun. This beam then travels through the length of the microscope cylinder‚ which contains the lenses‚ the specimen chamber‚ and the image-recording system. Two types of electron lenses are used‚ electrostatic and electromagnetic

Answer to Questions and Problems 1) In a strain gauge bridge‚ what does (a) a negative reading on the zero centered meters imply? (b) a positive reading on the zero centered meters imply? - A negative reading on the zero centered meter implies that the strain gauge is under compression. Whereas‚ a positive reading implies that the strain gauge is under tensile / tension. 2) Beside strain gauge transducers‚ what other transducers can be used in a bridge circuit? - Besides strain gauge transducers

Home is Where the Heart is In Ghost Hunter’s recent episode Home is Where the Heart is‚ the ghost hunter team heads to Beardslee Castle in Little Falls‚ NY. Some interesting facts about this castle is that the owner had hanged himself in the house. Along with the hanging other individuals have died in the house. The team investigates to see if they can debunk any of the reported occurrences. The Ghost Hunter team wires the castle/restaurant with video surveillance equipment. By doing this

Abstract: One is to determine the gap energy of cadmium sulfide semiconductor thin film using the equation: Eg = h.c/ is the signal of the long wavelength limit of the absorption peaks (measured in the lab). The reaction between cadmium sulfide and NH3‚ in the presents of thiourea yield a of 579(nm). The % error of the reaction is 1.24%. Introduction: There are 3 types of metals for electricity conducting: metallic conductor‚ semiconductor‚ and superconductor. Metallic conductors

Physics IN OUR DAILY LIVES “Any sort of technology which we uses IN our daily life is related to Physics.” Physics is the science of matter and its motion‚ space-time and energy. Physics describes many forms of energy - such as kinetic energy‚ electrical energy‚ and mass; and the way energy can change from one form to another. Everything surrounding to us is made of matter and Physics explains matter as combinations of fundamental particles which are interacting through fundamental forces. It will
