Question

a doctor uses an instrument(s) that emits light and allows the doctor to view the inside of a patients intestine. what is the doctor most likely using? a telescope a microscope laser beams fiber optics

Explanation:

• A telescope is used for viewing distant objects in space or far - off terrestrial objects, not for looking inside the human body.
• A microscope is used for viewing very small specimens (like cells) on slides, not for internal body cavities like the intestine.
• Laser beams are used for cutting or cauterizing tissues, not for viewing the inside of an intestine.
• Fiber optics can transmit light and images. In medicine, endoscopes (which use fiber optics) are used to view the inside of body cavities such as the intestine.

Answer:

fiber optics
