The speed at which the RADAR beam travels is indeed identified as the speed of light. RADAR technology operates by emitting electromagnetic waves, which include a spectrum of frequencies, such as microwaves. These electromagnetic waves travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second).

The other options do not accurately represent the nature of RADAR beams. Sound travels through a medium like air or water at a much slower speed than light, around 343 meters per second in air. Electricity refers to the flow of electric charge, which also does not correlate with the travel speed of electromagnetic waves used in RADAR systems. Lastly, magnetism is a characteristic of certain materials and fields but does not describe a speed; rather, it describes an interaction of forces. Therefore, the correct understanding of RADAR technology and its operation confirms that the RADAR beam travels at the speed of light.
