What is not true about Radar?
- a)Radar is an object detection system which uses sound waves to determine the range, altitude, direction, or speed of objects.
- b)The radar dish or antenna transmits pulses of microwaves which bounce off any object in their path.
- c)It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.
- d)The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter.
Correct answer is option 'A'. Can you explain this answer?

Explanation: Radar (Radio Detection And Ranging)
- Radar is an object detection system which uses radio waves to determine the range, altitude, direction, or speed of objects.
- It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.
- The radar dish or antenna transmits pulses of radio waves or microwaves which bounce off any object in their path.
- The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter.

Radar: A Brief Explanation
Radar, short for Radio Detection and Ranging, is a technology that uses radio waves to detect and locate objects. It is widely used in various fields such as aviation, maritime, meteorology, and military for object detection, tracking, and navigation purposes. However, option A is not true about radar. Here's an explanation of why:
Explanation:
1. Radar uses radio waves, not sound waves:
- Radar is an object detection system that uses radio waves, not sound waves, to determine the range, altitude, direction, or speed of objects.
- Sound waves are used in SONAR (Sound Navigation and Ranging) systems, which are primarily used underwater.
2. Radar transmits and receives radio waves:
- The radar system consists of a transmitter and a receiver.
- The radar dish or antenna transmits pulses of radio waves, typically in the microwave frequency range.
- These waves bounce off any object in their path and are received back by the radar dish or antenna.
3. Radar can detect various objects:
- Radar can be used to detect a wide range of objects, including aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.
- It is particularly useful in situations where direct line-of-sight visibility is limited.
4. Radar measures the return of energy:
- When the transmitted radio waves encounter an object, a tiny part of the energy is reflected back towards the radar dish or antenna.
- The radar system measures the time it takes for the reflected waves to return, allowing it to determine the range and other parameters of the object.
In conclusion, option A is not true because radar uses radio waves, not sound waves, for object detection.
