dc.description.abstract	Employing a law of weak acoustic wave, the ratio of population density N2/N1 with time for the Ca II H and K lines appropriate for the solar quiet chromosphere have been calculated. This has been done by solving the equations of radiative transfer and statistical equilibrium for two level plus continuum atom simultaneously. From the calculation it has been shown that even a small deposit of weak acoustic wave energy can enhance the emission peak of resonance lines.	en
