Abstract: 
uvbybeta photometric observations of the delta Scuti type star beta Cassiopeiae are presented. Analysis of the data using both Fourier Transform and classical O-C methods establishes beta Cas as a monoperiodic pulsator with a period of 0.10091d. The physical parameters of this star are determined. The analysis of the phase shifts between observed light and colour variations suggests that beta Cas can be a nonradial pulsator, but a discrepant amplitude ratio DELTA (b - y)/DELTA y is observed.
