What device is used for internal inspection of hard-to-see areas?

• A. Borescope
• B. Endoscope
• C. Snorkel
• D. Periscope

Answer: (A)

When you need to look into a space you can’t see directly, you use a tool that can be inserted into openings and show you the inside. A borescope is built for this job: a slender tube with optics at the tip and a light source, often connected to a display or eyepiece, so you can view the interior surfaces without taking the part apart. It can be rigid or flexible to reach different shapes and tight spots like engine bores, pipes, or dryer ducts. The other options serve different purposes: an endoscope is mainly used for medical examinations (though industrial variants exist, the term is most associated with healthcare), a snorkel is for underwater breathing, and a periscope is for seeing around corners or over obstacles. So the device intended for internal inspection of hard-to-see areas is the borescope.
