Final answer:
Of the pairs provided, the incorrect one is X-rays - Transmitting data through fiber optic cables. Fiber optic communication actually uses light in the infrared and visible ranges, not X-rays, which are used in domains like medical imaging.
Step-by-step explanation:
The question is related to the uses of different types of electromagnetic (EM) waves in communication. Specifically, it is asking which pair of EM wave type and its use in communication is not correct. EM waves are instrumental in different aspects of daily life, from broadcasting radio and television signals to cooking and medical applications. Radio waves generally refer to EM waves with wavelengths greater than about 0.1 m and are commonly used for audio communications such as AM and FM radio, cellular telephones, and TV broadcasts. Microwaves, which are a type of radio waves, are used in microwave ovens to heat food but are also used for WiFi, among other communication technologies. Infrared waves are typically employed for transmitting data between devices through remote control technology. X-rays, on the other hand, are not used for transmitting data through fiber optic cables. Fiber optic communication uses a different portion of the EM spectrum, which is light, commonly using the infrared and visible ranges. The correct use of X-rays i in medical imaging, among other scientific and industrial applications.
