Explanation:The type of light technology being described is fiber optic technology. Fiber optic cables are used to transmit light through the arthroscope, allowing the doctor to illuminate the knee joint during the examination. Fiber optics use thin strands of glass or plastic fibers to transmit light signals, providing a flexible and efficient way to deliver light to the desired location. In the case of the arthroscope, the fiber optic cable is inserted through the tiny incision and delivers the light to illuminate the joint, enabling the doctor to visualize and examine the knee. Fiber optic technology is commonly used in medical procedures like arthroscopy to provide illumination and enhance visibility during examinations or surgeries.
