    Check what you remember

    Read the wording for your board, then hide it and explain Photon energy in your own words. Rough notes are fine. This is a self-check, with no mark or grade.

    Reference: AQA

    The relationship E = hf links photon energy to frequency, while intensity relates to the rate of photons rather than to the energy of each photon.
    AQA · Interference (study guide)
    The amount of energy carried by a photon, determined by the frequency of the radiation: E = hf.
    OCR · Photons (study guide)
    The energy hc/λ of the light emitted by the LED, equal to the energy lost by the electron.
