We have studied scalar, electromagnetic and gravitational perturbations ofthe four-dimensional Reissner-Nordstr\"{o}m-like black holes with a\textit{tidal charge} in the Randall-Sundrum braneworld. The quasinormal modesof these scalar, electromagnetic, as well as axial and polar gravitationalperturbations, have been studied in both normal and eikonal regimes.Calculations have shown that the black holes on the Randall-Sundrum brane arestable against scalar, electromagnetic and gravitational perturbations.Moreover, we determine the grey body factor, giving transmission and reflectionof the scattered waves through the scalar, electromagnetic and gravitationaleffective potentials. It has been shown that the scalar perturbative fields arethe most favorite to the reflected as compared to the latter. With increasingvalue of the tidal charge ability of the all perturbative potentials to reflectthe waves decreases. Our calculations in low- and high-frequency regimes haveshown that black holes on the braneworld always have a bigger absorption crosssection of massless scalar waves than the Schwarzschild and standardReissner-Nordstr\"{o}m black holes.
