Communication and navigation satellites would be impossible without radio waves, as would modern aviation — an airplane depends on a dozen different radio systems. The WiFi networks that we depend on at work, home and school also rely completely on radio waves for data transmission. The funny ...
Some police are now using a laser technique to measure the speed of cars. This technique is called lidar, and it uses short pulses of light instead of short pulses of radio waves. See How Radar Detectors Work for information on lidar technology. CW Radar vs. Pulse Radar While we've foc...

fMRI is based on the same technology asmagnetic resonance imaging(MRI) -- a noninvasive test that uses a strong magnetic field and radio waves to create detailed images of the body. But instead of creating images of organs and tissues like MRI, fMRI looks atbloodflow in the brain to detect...
PURPOSE: An instruction for a radio wave apparatus in the same frequency is provided to transmit and receive distinguishing signals using a cable. CONSTITUTION: Distinguished two signals are combined. Images, sound, or various signals are generated in each apparatus. A television or a radio ...
thanks to the small size, lack of windows and hanging clothes. If you have to record instruments or voice-over with absolutely zero prep time, use the closet as your best bet. Obviously, you can't do things like record with a drum kit or piano, so this workaround has major drawbacks....
How Ham Radio Works How Bluetooth Works How does an EPIRB distress radio work? Do radio waves pose a health threat? Why do all FM radio stations end in an odd number? Why do some radio stations come in better at night? What is low-power FM? Why can't I use my cell phone on airp...
of the wireless card, let’s see how it work. A WiFi hotspot, usually a wireless router or access point, is the old-fashioned method of first receiving information from the Internet: via wires. Then, it converts the data from the binary form (computer code 1s and 0s) to radio waves...
A remote control works by sending out infrared waves that are picked up by the TV set. These infrared waves form a unique pattern, which is picked up by the TV and helps it recognize what action to take. Do remotes work through walls? Modern IR remotes are designed to send infrared li...
Microwave ovens cook foods by injecting them with, surprise, microwaves—a form of energy. These electromagnetic waves are invisible to the human eye and fall between radio waves, which are longer in wavelength, and infrared waves, which are shorter. Inside the guts of a microwave, a device ...
