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 ...

Scatter radiation - ANSWER-- form of secondary radiation - result of xray photon deflected in all directions travelling to all parts of client's body and to all areas of the op - detrimental to client and radiographer Compton scatter - ANSWER-- Evidence of ionization - xra photon collides w outer shell + gives up part of its energy to eject electron from it's orbit - ejected electron is known as compton or recoil electron Coherent scatter - ANSWER-- unmodified scatter - when low ene...

Photoelectric effect correct answers -When light of a sufficiently high frequency (typically blue to ultraviolet light) is incident on a metal in a vacuum, the metal atoms emit electrons. -albert einsteins 1905 explanation of the photoelectric effect won him the nobel prize. -Electrons liberated from the metal produce a current. -light beams of greater intensity produce larger current in this way. -higher the intensity of the light beam, the greater the number of photons per unit t...

BIO 204 Principles of Biology I Midterm Review (upcoming midterm exam 2024 prep) Athabasca University Chapter 1 1. describe the physical nature of light, and describe its dual nature of waves and particles. Light is composed of photons which are composed of 2 wavelengths called electromagnetic radiation. Both wavelength are on a 90 degree angle from each other. We can only see a small portion of the electromagnetic wavelength (visible light) 2. describe how light interacts with matte...
