Abstract
Classical-like, Wehrl's entropies of various quantum states of light a re calculated and investigated as functions of the average value of th e photon-number operator. Qualitatively similar behavior of the Wehrl entropies, corresponding to quantum states with quite different proper ties, is observed. A type of damping of the Wehrl entropies for states with high coherent components is pointed out and discussed.
