- a. Gives it better axial resolution
- b. Improves the lateral resolution of the transducer
- c. Kills all the bacteria and viruses
- d. Kills pathogens and destroys the transducer
2. Which of the following is defined as the minimum distance two reflectors can be, parallel to the beam, and still appear on the screen as two dots?
- a. Range resolution
- b. Angular resolution
- c. Contrast resolution
- d. Transverse resolution
3. Which of the following describes the result of destructive interference?
- a. The resulting wave is much larger than the original wave
- b. The resulting wave is a little larger than the original wave
- c. The resulting wave is smaller than the original wave
