  • Photon

    A particle of electromagnetic radiation, representing a quantum of light.
  • Planck's Constant

    A fundamental constant (6.626 x 10^-34 Js) used to calculate photon energy.
  • Frequency

    The number of wave cycles per second, measured in hertz, affecting photon energy.
  • Wavelength

    The distance between successive wave peaks, inversely related to photon energy.
  • Energy

    The capacity to do work, calculated for photons using frequency or wavelength.
  • Hertz

    The unit of frequency, equivalent to one cycle per second.
  • Quantum

    A discrete quantity of energy proportional to the frequency of radiation.
  • Speed of Light

    A constant (c) used in photon energy calculations, approximately 3 x 10^8 m/s.
  • Avogadro's Number

    A constant (6.022 x 10^23) representing the number of entities per mole.
  • Joules

    The SI unit of energy, used to express photon energy.
  • Electromagnetic Radiation

    Energy propagated through space as waves, including visible light.
  • Mole

    A unit representing 6.022 x 10^23 entities, used in photon energy calculations.
