Stromgren photometry of three double mode high amplitude Beta Scuti stars
uvby-beta photoelectric photometric observations of the threedouble-mode high-amplitude Beta-Scuti stars AE UMa, RV Ari and BP Pegare presented. Periodogram analyses are performed using the FourierTransform Method. In all three stars the power spectra are complex, anda large number of frequencies are identified. For each star, all thesefrequencies are shown to be harmonics or combinations of two mainfrequencies nu1 and nu2 corresponding to the fundamental and firstradial pulsation modes, respectively. Intrinsic b - y, m1, and c1 valuesare derived and the physical parameters of these stars are determined.
