Recently, it has been reported that a candidate for a quark star may have been observed. In this article, we consider quark stars with radiation radii in the reported range. We calculate nonradial oscillations of f, w, and w(II) modes. We find that the dependence of the f mode quasinormal frequency on the bag constant and stellar radiation radius is very strong and different from that of the lowest w(II) mode quasinormal frequency. Furthermore we deduce a new empirical formula between the f mode frequency of gravitational waves and the parameter of the equation of state for quark stars. The observation of gravitational waves both of the f mode and of the lowest w(II) mode would provide a powerful probe for the equation of state of quark matter and the properties of quark stars.
