Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

Introduction: Frederick Engels wrote The Origin of the Family‚ Private Property and the State with the purpose of providing a materialist analysis of how the family as we know it came to be with the rise of class society--and with it‚ the oppression of women. While Origin of the Family was written after Karl Marx ’s death in 1883‚ it was largely based on notes that Engels and Marx made on the research of anthropologist Lewis Henry Morgan‚ who had published Ancient Society in 1877‚ making him one

Water has many unique properties that make life possible on Earth. One property is cohesion. The cohesion property is properly defined as the binding of water molecules by hydrogen bonds. Water has this property as a result of the chemical bonding between water. Cohesion of the strong hydrogen bonds allows the water molecules to stick together‚ almost as a unit of one. A force exerted on one of the molecules will be exerted on all of the adjacent molecules as a result of cohesion. Cohesion‚ often

2014 ! ! Physical and Chemical Properties! Purpose/Hypothesis:! • The purpose of this experiment is to investigate the chemical and physical properties of pure chemical substances. A property of a substance is some distinguishing characteristic. Some of the most common physical properties are color‚ odor‚ hardness‚ density‚ melting point‚ boiling point‚ and solubility in various solvents. For all of these properties‚ no chemical change takes place. Chemical properties describe the tendencies of a

Abstract: Dielectric properties of K2Pb(SO4)2 at different temperatures were studied with respect to frequency and the results were discussed. In our present work‚ K2Pb(SO4)2 was synthesized at 80°C using potassium sulphate and lead nitrate of high purity as the starting material. The structural property of the material was studied by X-ray diffraction (XRD). The functional groups present in the material were identified using Fourier Transform Infra-Red (FTIR) Spectroscopy. The thermal behaviour
