Electrons Waves and Photons Study guides, Class notes & Summaries

LRA 211 Final Review Study Guide (223/2024) Graded A+ The earliest atomic theory based on an arrangement similar to the solar system is attributed to Rutherford. The three fundamental particles of the atom are the neutron, electron, and proton. The atomic nucleus contains protons and neutrons. The component of the nucleus that has a positive charge and mass is the proton. The electron shell closest to the nucleus is lettered "K". Which of the following is not part of the electromagnetic ...

Matter - Anything that occupy space and has mass Mass - Distinguishable characteristic of matter Mass - Quantity of matter that is described by its energy equivalent Atoms - All matter is composed of fundamental building blocks Kilograms - How is mass measured? Meters - What does length measure? Seconds - What does Time measure? Weight - Force on a body caused by the pull of gravity on it Energy - Ability to do work Potential Energy - The ...

Production of X-Ray 1. Push exposure button 2. Electrons are produced @ cathode 3. Accelerated across to anode 4. strike anode = heat + x-ray energy 5. X-ray exit window through aluminum disk (remove long wave length x-rays) 6. Size is restricted by lead collimator 7. Travels down PID X-ray machine - Control panel: on/off - Extension arm - Tubehead: Metal housing, insulating oil, tube, transformer, aluminum disk, lead collimator, PID X-ray tube - Glass vacuum tube - Lead gl...
