  1. Electromagnetic Induction vs. Electromagnetic Radiation - Physics …

    Nov 9, 2009 · So, I have a few questions regarding some of the laws of electromagnetism. While I was in school, one of my classes was Electrodynamics (as an ECE undergrad). We discussed …

  2. Interaction of EM radiation with Glass - Physics Forums

    Mar 9, 2023 · The discussion focuses on the interaction of electromagnetic (EM) radiation with glass, specifically standard glass's response to infrared (IR), visible light, ultraviolet (UV), and …

  3. How short can electromagnetic radiation become ... - Physics Forums

    Jun 12, 2019 · The discussion confirms that there is no known physical limit on the wavelength of electromagnetic radiation, asserting that gamma rays have no lower bound. Wavelengths …

  4. Is all EM radiation light? - Physics Forums

    Dec 16, 2024 · Are gamma rays, x-rays, microwaves, and radio waves considered as light? What about UV and infrared radiation? I'm getting conflicting definitions. They all travel at c (in a …

  5. Is There a Maximum Wavelength for Electromagnetic Radiation?

    Aug 29, 2010 · Is there any lower limit on the frequency of electromagnetic radiation? I imagine that beyond a certain frequency it becomes impossible to detect, but is...

  6. EM waves have no mass but they do have momentum?

    Mar 26, 2022 · The discussion centers on the concept of momentum in relation to electromagnetic (EM) waves, specifically addressing the misconception that mass is a prerequisite for …

  7. Electron absorbs photon, but what happens to the photon?

    Mar 15, 2025 · If the electron absorbing the photon causes it to change from waveform to particle ? Then what causes the photon to change from waveform to particle when observed ? (That is …

  8. Does Electromagnetic radiation travel faster than the speed of …

    Sep 29, 2012 · Therefore, I have to conclude that Electromagnetic radiation actually travels faster than the speed of light, at least in a vacuum. You seem to think radiation follows a "wavy path" …

  9. Is electromagnetic radiation a form of kinetic energy?

    Oct 7, 2016 · EM radiation is unique in that it is all kinetic energy. The equation for kinetic energy that you quoted above is a nonrelativistic approximation which cannot be used for light.

  10. What determines which metals will reflect or absorb …

    Jul 30, 2012 · The discussion centers on the differing reflective properties of nickel and gold concerning infrared electromagnetic waves. Nickel reflects infrared effectively due to its oxide …
