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 ...
How are electromagnetic waves different than all other waves? How is beta radiation formed? How is ionizing radiation used? What are the uses of electromagnetic radiation? Explain the concept of an electromagnetic field and how it relates to solar radiation. How are electromagnetic wav...

CT scans and MRIs are both used to capture images within your body. The biggest difference is that MRIs (magnetic resonance imaging) use radio waves and CT (computed tomography) scans use X-rays. How many types of tomography are there? There are2 basic types of tomography: linear and nonli...
Radio waves are the backbone of nearly all modern media technology, from TV to smartphones to wireless internet. Yet, they're actually a simple technology.
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 sp...
Where Are You? Once fast radio bursts (FRBs) were confirmed, scientists began to speculate on the possible causes. Could it be just a flare? Active magnetars? A neutron star collision? Black hole evaporation? Alfven waves? Cosmic string vibrations? Pinpointing the source has proven to be a ...
Light is part of the electromagnetic spectrum — it's made of high-frequency electrical and magnetic waves. These waves are fairly complex, but you can imagine them as similar to waves on water. They have peaks and troughs, and they travel in a straight line until they encounter an ...
Radio waves are much faster, longer, and more frequent than ocean waves, however. Their wavelength is typically hundreds of meters—so that's the distance between one wave crest and the next. But their frequency can be in the millions of hertz—so millions of these waves arrive each second...
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...
