Which of the following is NOT one of the steps to Radar working?

The correct answer is that the transmission of sound waves is not one of the steps in the radar working process. Radar operates on the principle of radio waves, not sound waves. It utilizes electromagnetic waves to detect the presence, distance, speed, and direction of objects, such as aircraft or weather formations.

In the functioning of radar, the process begins with the transmission of radio waves. These waves travel through the air until they encounter an object, which is where the interaction occurs. The radar system then receives the reflected signals from these objects, enabling it to determine their location and characteristics. Finally, the data that has been received is displayed and analyzed, allowing operators to interpret the information gathered.

Thus, since radar relies on electromagnetic waves rather than sound waves, the step involving the transmission of sound waves does not belong to the radar working process.
