Infrared waves, or IR radiation, is a type of electromagnetic radiation that has a wavelength greater than the wavelengths in the visible part of the electromagnetic spectrum; they are located adjacent to visible region and the microwave region at its other end. Infrared radiation can be emitted ...

You might have noticed that the AM radio antenna in your car is not 300 feet (91 meters) long — it is only a couple of feet long. If you made the antenna longer it would receive better, but AM stations are so strong in cities that it doesn't really matter if your antenna is the...
As WLANs use radio signals to transmit service data, radio waves in the air are attenuated due to the impact of the surrounding environment. If the Wi-Fi speed is low, check the Wi-Fi signal strength. The strength of Wi-Fi signals received by a STA directly affects the Wi-Fi s...
Larger components such as power transformer, speaker, and antenna are mounted either on the PCB or cabinet with screws or metal spring tabs. The case that houses the radio can be made either of plastic or aluminum. Plastic cases are made from pellets that are melted and injected into a mo...
sounder uses radar to find underground liquid reserves. Other cameras monitor clouds and dust storms. All the information from the Mars Reconnaissance Orbiter is relayed back to Earth through X-band and Ka-band radio waves that are picked up by theDeep Space Network antennain Canberra, Australia...
If your walls are insulated or made of brick or stone, you already have some soundproofing in place. When you need extra sound blocking, though, you can approach it two ways: from the front or the back. Wall-mounted acoustical tiles, wall panels, fabrics and vinyl barriers are designed ...
Are NFC payments secure? How are businesses using NFC technology? Let’s look at all these questions and explore some common applications for NFC tech. How Do NFC Tags and NFC Chips Work? NFC tags work like any other RFID tag to communicate over radio waves. Two NFC-enabled devices — ...
The FRBs are a trillion times more energetic than pulsars observed in our own galaxy, so a truly extreme process needs to produce the bursts.” Putting the Universe on the Scale So, how exactly do radio waves help weigh the universe? As radio waves travel through intergalactic space, they...
Tech Talk: Radio Waves in Astronomy Radio waves are electromagnetic waves (light), but we can't see them. They have wavelengths between 1 millimeter (one-thousandth of a meter) and 100 kilometers (one kilometer is equal to one thousand meters). In terms of frequency, this is equivalent to...
