Question

why are networks of cables not used to send information from a remote control to a television? a. microwaves cannot travel through cables. b. infrared radiation cannot travel through cables. c. the information needs to travel only a short distance. d. cables slow down the speed at which information is communicated.

Explanation:

Remote - controls use infrared radiation to send signals to televisions. Since the distance between a remote - control and a television is usually short (a few meters), there is no need for a complex cable network. Infrared signals can effectively transmit information over this short range.

Answer:

C. The information needs to travel only a short distance.
