We investigate the periodic motion of the reaction products of the dissolution of a steel ball in nitric acid in a magnetic field. Video recording is used in both the natural light and the coherent radiation of a red semiconductor laser. The video recording results are processed using the Fourier transform. Coherent-radiation photography and its processing with speckle-contrast methods are also used. As a result of the work, we find the characteristic frequencies of the periodic motion of the reaction products and the distribution of their relative velocities.

Key words: magnetohydrodynamics, electrochemical reactions, periodic motion, Fourier transform, coherent light, speckles.
