Answer 2

D. Detecting the presence of humans trapped under collapsed buildings is one example of the use of an infrared sensor.

• Infrared sensors can detect infrared radiations from a body. These radiation-sensitive devices can also measure the heat being emitted by an object.
• IR waves are a part of the electromagnetic spectrum. These have lower energy than visible rays.
• Humans radiate heat waves (IR waves). Thus a human trapped under collapsed buildings can be detected using IR sensors.
• Bar scanners work by converting optical signals into electric signals.
