While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, oscillating material does not move far from its initial equilibrium position.]]> 2017-03-01 17:05:17 UTC https://padlet.com/desih1211/azg16blepluc/wish/157092726 desih1211 https://padlet.com/desih1211/azg16blepluc/wish/157093080 A mechanical wave is a wave that is not capable of transmitting its energy through avacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.]]> 2017-03-01 17:05:56 UTC https://padlet.com/desih1211/azg16blepluc/wish/157093080 desih1211 https://padlet.com/desih1211/azg16blepluc/wish/157093378 Some of the most common examples of mechanical waves are water waves, sound waves, and seismic waves. There are three types of mechanical waves: transverse waves, longitudinal waves, and surface waves.]]> 2017-03-01 17:06:39 UTC https://padlet.com/desih1211/azg16blepluc/wish/157093378 desih1211 https://padlet.com/desih1211/azg16blepluc/wish/157093566 For transverse waves the displacement of the medium is perpendicular to the direction of propagation of the wave. A ripple on a pond and a wave on a string are easily visualized transverse waves.

Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. "Near infrared" light is closest in wavelength to visible light and "far infrared" is closer to the microwave region of the electromagnetic spectrum. The longer, far infrared wavelengths are about the size of a pin head and the shorter, near infrared ones are the size of cells, or are microscopic.

Cellphones use radio frequency waves to transmit sound through the speaker and the microphone.

Infrared is also a type of wave that transmits a lot of heat. When you put your hand near to, but not touching, something and it feels warm, it's because of infrared waves coming out of it. All hot objects produce infrared. In fact, you're producing infrared waves right now. Infrared waves can also be used to create heat-sensitive and night vision cameras.

But they're not just for FM and AM radio. They're also used to broadcast television signals, and they're how mobile phones work - your voice is sent through radio signals. Radio waves are also used for radar, which is why both words start with the same three letters. Radar is extremely important in military operations and can also be used in speed cameras and speed guns.]]> 2017-03-01 17:14:16 UTC https://padlet.com/desih1211/azg16blepluc/wish/157096260 desih1211 https://padlet.com/desih1211/azg16blepluc/wish/157096582  Since microwaves aren't that different from radio waves, they've also been used for communications, especially for extending TV signals to larger distances.]]> 2017-03-01 17:14:59 UTC https://padlet.com/desih1211/azg16blepluc/wish/157096582 desih1211 https://padlet.com/desih1211/azg16blepluc/wish/157096799 Ultraviolet waves have their uses too, but they're also a bit of a pain. That's because the sun produces a lot of ultraviolet and is a common cause of skin cancer. When powerful enough, UV can damage your skin. Getting a sun tan might be a fun-sounding use of UV, but because of the risks, it's a bad idea. More positive uses include the fact that UV can sterilize and disinfect medical instruments (or anything else, for that matter), killing bacteria and viruses. And ,UV also lights up fluorescent materials; highlighter pens are brighter and more useful because of this effect. This property can be used to check if money is real or counterfeit by hiding things in it that light up under UV.
