Mindblown: a blog about philosophy.

  • Electron beam

    The stream of electrons that moves from the cathode to the anode within an X-ray or vacuum tube. These electron streams are also referred to as cathode rays.  

  • Electromagnetic energy

    The energy linked to cosmic rays, gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio or electric waves.  

  • Electromagnetic

    Pertaining to the combined electric and magnetic fields associated with movement of electrons through conductors.  

  • Electrodynamics

    A field of physics that focuses on the behavior of electric charges in motion or undergoing dynamic changes.  

  • Electric flux

    A region of electrical sensitivity that exists in the vicinity of electric field lines.  

  • Effective voltage

    The magnitude of alternating current that would perform an equivalent amount of work as its corresponding direct current value. The effective voltage is approximately 0.707 times the maximum voltage.  

  • Effective half-life

    The decay period of a radioisotope within a living organism, which arises from the interplay between radioactive decay and biological removal.  

  • Effective focal spot

    The perpendicular projection or the apparent size of the actual focal point as it is displayed on the film. The x-rays depart from the rectangular real focal point and seem to originate from a significantly smaller square region. Essentially, the x-rays are discharged from either the square region or the effective focal point.  

  • Effective current

    The magnitude of alternating current that accomplishes an equivalent amount of work as the corresponding value of direct current. The effective current is approximately 0.707 times the maximum current.  

  • Effective atomic number

    A numerical value obtained by combining the atomic numbers of a compound or mixture, reflecting its composition. For instance, various sections of the human body exhibit different values: fat 6.3, muscle 7.4, water 7.4, and bone 11.6. These variations in atomic number arise due to differences in tissue opacity and the depth of material.
