all the light shown in the surfaces. They also radiate almost perfectly. The temperature of the black body object determine the distribution of colors or wavelengths in the admitted line. A good example of black body radiation is the heat inside a stove‚ electromagnetic radiation light and heat exist in a form of standing waves‚ waves like the vibration of a guitar string is attached in both ends. The ends of the standing waves do not move‚ the are attached to the side of the stove‚ and many waves

to their ground state‚ several distinct energy emissions occur. Electrons may become excited when a sample of matter is heated or subjected to an electrical current. The energy that electrons emit when returning to the ground state is electromagnetic radiation‚ or EMR. Sometimes the EMR can be seen as visible light. In 1900‚ Max Planck studied visible emissions from hot glowing solids. He proposed that light was emitted in packets of energy called quanta and that the energy of each packet was

XRD – X-Ray Diffraction X-ray diffraction (XRD) is a powerful non-destructive technique for characterizing crystalline materials. It provides information on structures‚ phases‚ preferred crystal orientations (texture)‚ and other structural parameters‚ such as average grain size‚ crystallinity‚ strain‚ and crystal defects. X-ray diffraction peaks are produced by constructive interference of a monochromatic beam of X-rays scattered at specific angles from each set of lattice planes in a sample. The

Opportunities such as surgery‚ medicine treatments‚ and multiple therapy options. Radiation therapy has impacted many people’s lives just in the last few years. Cancer patients especially‚ have been given another chance at life through a few treatment rounds. In the past to remove cancerous tumors and small masses‚ surgery was the only option to improve those patients lives; with advances in technology and medicine‚ radiation therapy has become a very likely option for these patients. An option that
