  This paper reports a new reading for wavelets, which is based on the
classical 'De Broglie' principle. The wave-particle duality principle is
adapted to wavelets. Every continuous basic wavelet is associated with a proper
probability density, allowing defining the Shannon entropy of a wavelet.
Further entropy definitions are considered, such as Jumarie or Renyi entropy of
wavelets. We proved that any wavelet of the same family has the same Shannon
entropy of its mother wavelet. Finally, the Shannon entropy for a few standard
wavelet families is determined.
