Answer to Question 1

ANS: C
The free electron laser creates a light beam as a series of rapid superpulses of high energy and short duration with minimal thermal damage. These light beams can fragment calculi.

Answer to Question 2

ANS: D
The objective lenses are available in various focus lengths ranging from 100 to 400 mm, with intervening increases by 25-mm increments. The 400-mm lens provides the greatest magnification.
