Graph (a) below describes the density versus time of a pressure wave traveling through an elastic medium. Graph (b) describes the density versus distance for the same wave A. Use graph (a) to find the period of oscillation of this wave and its frequency.

B. Use graph (b) to find the wavelength and the speed.
