Final answer:
The provided text describes different types of probes, including those used in scanning probe microscopy, scanning tunneling microscopes, endoscopic medical devices, and probes sent into planetary atmospheres like Jupiter's.
Step-by-step explanation:
The passage focuses on different types of probes used in various contexts, such as scientific exploration and medical diagnostics. One type of probe mentioned is used in scanning probe microscopy, scanning the surface of a specimen at a constant distance and measuring the sensitive current. Another is the scanning tunneling microscope, passing just above the specimen and utilizing a voltage bias to facilitate an electric current for imaging. Additionally, an endoscope is referred to as a probe in medical applications, illuminating and imaging the interior of the body. Finally, the passage references a space mission where a probe descends into Jupiter's atmosphere, providing data until it disintegrates due to the hostile environment.
