Homework Help: Graphing - photonic Energy Vs Frequency

  1. Aug 9, 2011 #1
    1. The problem statement, all variables and given/known data

    "What is the relationship between the energy of a photon and its frequency"

    then

    "Qualitively graph photonic energy versus frequency. No values are required. The Slope does not need to be specific."



    2. Relevant equations

    we are given a graph with no values, the frequency is on the X-Axis while the photonic energy is on the Y-Axis



    3. The attempt at a solution



    i have drawn a straight line at a diagonal, which goes through the origin, this would infact make the photonic energy directly proportional to the frequency.

    I am not sure if this is correct?, are you please able to assist me to achieve the correct answer

    thanks


    Mr. Fischer

    Sounds good. (What's the energy of a photon of given frequency?)

    What's the general relationship between photon energy and frequency?

    If the frequency increases, the photon energy will increase

    directly proportional?

    Yes. The energy of a photon is related to the frequency of the radiation by Planck's relationship: Energy = Planck's constant X frequency.
