    Planck’s quantum theory:

    According to this theory:

    1. Energy emitted or absorbed is not continuous, but is in the form of packets called quanta .In terms of light it is called as photon.
    2. Each photon carries an energy which is directly proportional to the frequency of wavelength i.e. E depends upon v (nu).
      1. Or E=hv (where v is frequency)
      2. Value of h =6.634 x 10-34Jsec
    3. Energy associated with no of packets is given by:

    E=nhv (where n is an integral multiple)

    This formula can also be written as:

    E = (nhc)/ (λ)

     (Because we know frequency=speed of light/wavelength)

    V = (c/ λ)
