PPT-Radiation: Energy in transit, either particulate or electromagnetic in nature

Radioactivity The characteristic of various materials to emit ionizing radiation Ionization The removal of electrons from an atom The essential characteristic of high energy radiations when interacting with matter.

Electromagnetic waves perpendicular waves combing the electric and magnetic fields. . Electromagnetic waves are produced when an electric charge vibrates or accelerates and can travel through empty space or through matter. . Energy that travels as a wave through space. Wavelength –. λ – distance between corresponding points on adjacent waves. Frequency – f – waves per second. Spectrum. Breakdown of electromagnetic radiation by increasing wavelength. Chapter 9: Electrons in Atoms and the Periodic Table. Learning Goals. Compare the wave and particle natures of light.. Define a quantum of energy, and explain how it is related to an energy change of matter.. Chapter 9 . Trapped in a Newtonian Universe. Though Newton’s Apple and Calculus are helpful, his theories are only as good as the next round of evidence.. Now we have electromagnetic fields and energy without tiny solid particles.. . What do X­rays, light, microwaves, radio waves, and infrared have in common? . . EM Radiation. Radiation can be described as the movement of energy through space. . There are many different sources of radiation that vary by intensity. . . Intro to Electro Magnetic Waves. (. or electromagnetic radiation). (or EMR). Electro-Magnetic Radiation is an interesting subject in physics in part due to the fact that we interact with EMR (electromagnetic Radiation) or technology that makes use of our understanding of electromagnetic Radiation to enhance our lives. . Radiation.  is a process in which energetic particles or energetic waves travel through vacuum or media. .. Radiobiology.  (also known as radiation biology) is the study of the action of ionizing radiation on living things.. March 25. June 18. September 26.
