Question

Jared is a criminal investigator. He is using a new "supersnoop" device that detects extremely small temperature changes and essentially lets him look through walls. Jared's device uses which type of technology?

A) Infrared
B) Ultraviolet
C) Microwave
D) Radiofrequency

Answer 1

Jared's 'supersnoop' device uses Infrared Radiation technology to detect small temperature changes and see through walls.

Step-by-step explanation:

Jared, the criminal investigator, is using a device that detects extremely small temperature changes to essentially 'see' through walls. This technology is based on Infrared Radiation. Infrared radiation is particularly sensitive to thermal motion as well as vibration and rotation of atoms and molecules, making it ideal for detecting small temperature differences.

In practical applications, Infrared Technology is used in various fields including military night scopes, medical thermographs, and for detecting heat leaks in homes.

In Jared's case, the 'supersnoop' device likely uses infrared technology to detect the subtle differences in heat emitted through walls, which can betray the presence of people or objects behind them due to the fourth-power dependence of radiant power on temperature (T4).
