Answer to Question 1

Energy, in the form of sound waves, is transmitted into the patient where it reflects off the organs and other internal structures. The returning echoes form an image of the particular structure.

Answer to Question 2

B
Explanation: A) LASIK is a surgical procedure to correct myopia, not a test.
