What is the speed of RADAR?

The correct answer is based on the fundamental principle that RADAR (Radio Detection and Ranging) technology relies on electromagnetic waves, which travel at the speed of light. In a vacuum, this speed is approximately 299,792 kilometers per second, which is equivalent to about 186,000 miles per second. This is a well-established fact in physics, as electromagnetic waves, including those used in RADAR systems, propagate at this constant speed.

While it is true that environmental factors, such as humidity, temperature, and obstacles, can affect the effective range and clarity of RADAR signals, they do not alter the intrinsic speed of light itself. Therefore, the option that states 186,000 miles per second accurately reflects the speed of the electromagnetic waves utilized in RADAR systems, making it the most accurate choice.
