What else can I help you with?
When a police officer uses radar for speed control the officer is using what kind of electromagnetic waves?
radio waves
How fast do cell phone waves travel through the air?
Cell phone transmission uses shortwaves (120 MHz to 1000MHz) to transmit its signals, these waves are Electro-magnetic waves (just like light); thus, they travel at the speed of light: 299,792,458 m/s or 670,616,629 mph.
What instrument uses radio waves to penetrate gas and dust of the universe?
stop
What appliance uses small sound waves?
Oh, dude, you're looking for an appliance that uses small sound waves? That would be a microwave! It heats up your leftovers with those tiny sound waves, like a little culinary concert in your kitchen. Just make sure you don't accidentally turn your burrito into a rock concert, unless you're into that kind of thing.
What type of wave uses a medium?
All waves of the EM. spectrum e.g. Radio waves Microwaves Light waves X-rays Gamma rays Cosmic Rays etc. Technically gravity waves and a couple other waves that relate to inter- and extra- atomic bonds
Air craft detecting device?
Radar is an object-detection system that uses radio waves to determine the range, altitude, direction, or speed of objects. It can be used to detect aircrafts.
Which rays does radar use?
Radar uses radio waves for detecting and tracking objects. These radio waves are emitted by the radar system and bounce off nearby objects, with the reflected waves then being detected by the radar receiver to determine the object's location and speed.
Are radars and gps one in the same?
No, radars and GPS are not the same. Radar (Radio Detection and Ranging) uses radio waves to detect objects and determine their distance, speed, and direction, commonly used in aviation and weather monitoring. GPS (Global Positioning System) relies on signals from satellites to provide location information to users on the ground, enabling navigation and positioning. While both technologies use radio waves, their functions and applications are distinct.
What are infa-red waves used for?
Infrared waves are special waves that helps you get rid of wrinkles.
When a police officer uses radar speed for control the officer is using what kind of electromagnetic waves?
Radar uses radio waves.
What type of wave uses a radar?
Radar uses electromagnetic waves, specifically radio waves, to detect the range, angle, or velocity of objects such as aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.
Why are radars circle shaped?
a radar uses a "parabolic" dish to capture the radio waves and because the shape is concave the waves hit the centre of the dish, the receiver is placed away from the centres facing the dish where the waves are reflected to it. The classic example is satellite dish receivers
How does sonar use echoes to locate objects?
Sonar uses echoes to locate objects by bouncing sound waves off them and detecting the echoes.
When a police officer uses radar for speed control the officer is using what kind of electromagnetic waves?
radio waves
When the police officer uses radar for speed control the officer is using what kind of electromagnetic waves?
radio waves
What is a device for detecting an underwater object called?
A device for detecting underwater objects is typically called a sonar device. Sonar uses sound waves to detect and locate objects underwater by measuring the time it takes for the sound waves to bounce off the object and return to the device.
What is the difference between sonar and echo?
Sonar is a technology that uses sound waves to detect objects underwater, while an echo is the reflection of sound waves off a surface back to the source. Sonar is used for navigation, communication, and detecting underwater objects, while an echo is a natural phenomenon that occurs when sound waves bounce off surfaces.
