Which principle regarding the design features of an ultrasonic transducer is true? * the higher the frequency of waves, the higher the visualization quality, but the lower the penetration depth the lower the frequency of waves, the higher the visualization quality, and the deeper the penetration the lower the frequency of waves, the lower the visualization quality, and the smaller the penetration depth the depth of penetration does not depend on any of the listed factors. the higher the frequency of waves, the lower the visualization quality, but the greater the penetration depth
