内容記述 | Elastic waves were generated in the ground by rotating an eccentric mass driven by an electric motor, and the phase differences of the waves at two places observed with two geophones and a cathode ray oscillograph., The geophenes set at the two places were connected by means of electric cables to the horizontal and vertical deflection plates of the cathode ray oscillograph. The shape of the orbit of the cathode ray then changed with the phase difference of the waves at the two places. The orbit became straight lines when the geophones were set at intervals of half a wave-length, one wave-length, and so on. The wave lengths were measured from the distance of the geophones, and the period of the waves from the number of rotations of the motor per minute. The relations between the wavelength and the period, or velocity, of the waves, are shown in the figures in the paper. Numerous other experiments were made in order to investigate the nature of the was, but, as in the case of D A. Ramspeck and G. A. Schulze (see their waves,•paper (Veroff. Degebo., Berlin, Ht. 6 (1938)), scarcely any conclusive results were obtained. | |||||
