Beams & Focusing 1. What is the overall shape of the sound beam? 2. Draw the sound beam and label: focus, near zone, near zone length (focal length), far zone, and focal zone. 3. What are the estimated widths of the portions of the beam? Label these on the sound beam diagram. 4. What is the aperture of the crystal? Based on the given beam characteristics: • Beam width at 20 cm depth is 10 mm Near Zone Length (NZL) is 10 cm • Focal Zone (FZ) is 5 cm Answer the following questions: 1. What is the aperture of the crystal? 2. What occurs at 10 cm depth? 3. What is the beam width at 10 cm depth? 4. At what depth does the Focal Zone (FZ) start? 5. At what depth does the Focal Zone (FZ) end?
