Question

an arthroscope can be inserted into a knee joint through a very tiny incision to help a doctor examine the knee. a light is transmitted through the scope to illuminate the joint. what type of light technology is being described?

Explanation:

An arthroscope uses optical fibers to transmit light. Optical fibers are thin, flexible strands that can carry light over long distances with minimal loss. They work based on the principle of total internal reflection. Light is guided through the fiber by bouncing off the inner walls. In the context of an arthroscope, this allows the light to be transmitted through the narrow scope to illuminate the joint for examination.

Answer:

Optical fibers (or fiber - optic technology)
