Figure 1 shows a simplified diagram of a piezoelectric transducer crystal used in a medical ultrasound scanner.

Figure 1: Cross-section of a vibrating piezoelectric crystal generating ultrasound waves in a coupling gel.

When an alternating electrical voltage is applied, the face of the crystal vibrates at high frequency as indicated by the arrows.

Describe how the vibrating face of the transducer crystal causes an ultrasound wave to travel through the adjacent coupling gel.
