Transverse waves: the movement of the particles are at right angles/ perpendicular to the motion of the energy.
Surface waves: particles travel in a circular motion.]]> 2017-02-22 18:32:32 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155554850 Speed of waves lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155558378 Wave motion is due to the spreading of the wave from where it begins. For a water wave, the water itself stays in the same average place. Therefore, to gauge the speed of a wave you measure how fast the wave spread, not how fast the water surface moves up and down.]]> 2017-02-22 18:41:15 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155558378 lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155561879 2017-02-22 18:50:32 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155561879 lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155565483 2017-02-22 19:00:03 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155565483 Relationship with technology lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155565660 example: The distance the electromagnetic wave can travel depends on the power of the signal , which is measured in watts. When taking a long trip in a car, you may have noticed that you can listen to your favorite radio station for an hour or so, and then the signal gradually fades out. A city in  another state can use the same frequency as the radio station in your hometown without interference, as long as the cities are farther apart than the reach of their signal]]> 2017-02-22 19:00:27 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155565660 Types of waves lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155570157 Radio wave:A radio wave is generated by a transmitter and then detected by a receiver. An antenna allows a radio transmitter to send energy into space and a receiver to pick up energy from space. Transmitters and receivers are typically designed to operate over a limited range of frequencies.
Microwave: is a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies 
between 300 GHz.Microwaves oven are fast efficient, they channel heat energy directly to the molecules into food. It heats food like the sun heats us which is used by radiation
Infrared: Infrared is a type of radiation, infrared light is part of the EM spectrum that people encounter most in everyday life, even though much of it goes unnoticed. Infrared light is invisible to human eyes , but people can feel it as heat.For example the Earth is full of infrared waves, these waves are emitted by anything which is capable of emitting heat.
Visible: The visible spectrum is the light that is visible to humans.We see because of the visible spectrum.
Ultraviolet: The ultraviolet is the  the light that has shorter wavelengths than visible light. Although we can't see them ,some insects such as bumblebees, can see them.
X-ray:A photon of electromagnetic radiation of very short wavelength, ranging from about 10 down to 0.01 galvanometers, and very high energy, ranging from about 100 up to 100,000 electron volts. X-rays could be used for photographs of bones.
Gamma wave: it's a penetrating electromagnetic radiation of a king from the radioactive decay of atomic nuclei.Gamma radiation  have been used in medicine to kill cancer cells. ]]> 2017-02-22 19:12:44 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/155570157 lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/156112845 2017-02-24 18:43:51 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/156112845 Examples lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/156113468 2017-02-24 18:45:46 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/156113468 Radio wave lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/156113638 We use radios to communicate from one place to another through the intervening media without wires.

These can be used to study human and animal body heat patterns, but more often, they are used as night-vision cameras. These have uses in warfare, as security cameras and in nocturnal animal research.]]> 2017-02-24 18:55:54 UTC https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/156116885 Visible lilianamunguia https://padlet.com/lilianamunguia/wtp1hwegv9tp/wish/156118129 We use visible light to see everyday.

In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels
In water waves, energy is transferred through the vibration of the water particles.
