Final answer:
Satellite television signals are transmitted in the B. microwave region of the electromagnetic spectrum, and devices designed by electronic engineers must be capable of receiving these microwaves.
Step-by-step explanation:
An electronic engineer who makes devices to receive television pictures from satellites must design these devices to receive microwaves. This is because television signals transmitted from satellites are primarily in the microwave region of the electromagnetic spectrum. The term radio waves can sometimes encompass microwaves due to their overlapping frequency ranges, but specifically for satellite communication, microwaves are used. These are the same type of electromagnetic waves utilized by microwave ovens and for transmission of many wireless communication signals like cellular telephones. According to the characteristics of the electromagnetic spectrum, microwaves lie between radio waves and infrared radiation with respect to their frequencies and wavelengths.
Microwaves are a type of electromagnetic radiation with wavelengths ranging from about 1 millimeter to 1 meter. They are used for various applications, including satellite communication and broadcasting.
These devices utilize antennas to capture the microwave signals transmitted from satellites and then convert them into electrical signals that can be processed to display the television pictures.
