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.]]> 2016-03-30 03:26:48 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103167528 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103167631 Electromagnetic waves are waves which can travel through the vacuum of outer space. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another.]]> 2016-03-30 03:28:59 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103167631 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103168049
Transverse waves cause the medium to vibrate at a right angle to the direction of the wave or energy being carried by the medium. Transverse waves have two parts—the crest and the trough. The crest is the highest point of the wave and the trough is the lowest. The distance between a crest and a trough is half of wavelength. The wavelength is the distance from crest to crest or from trough to trough.

It consists of multiple compression and rarefaction. The rarefaction is the farthest distance apart in the longitudinal wave and the compression is the closest distance together. The speed of the longitudinal wave is increased in higher index of refraction, due to the closer proximity of the atoms in the medium that is being compressed. Sound is considered a longitudinal wave.]]> 2016-03-30 03:38:09 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103168171 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103168252 This type of wave travels along a surface that is between two media. An example of a surface wave would be waves in a pool, or in an ocean, lake, or any other type of water body. There are two types of surface waves, namely Rayleigh waves and Love waves.]]> 2016-03-30 03:39:59 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103168252 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103168438 Waves transport energy, not matter. This makes them different from other phenomenon in physics. a wave is a traveling disturbance that travels through space and matter transferring energy from one place to another.]]> 2016-03-30 03:44:07 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103168438 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103168787 Energy Resources: Wave power. Ocean waves are caused by the wind as it blows across the sea. Waves are a powerful source of energy. The problem is that it's not easy to harness this energy and convert it into electricity in large amounts.]]> 2016-03-30 03:50:26 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103168787 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103169055 Special buoys, turbines, and other technologies can capture the power of waves and tides and convert it into clean, pollution-free electricity. Like other renewable resources, both wave and tidal energy are variable in nature. Waves are produced by winds blowing across the surface of the ocean.]]> 2016-03-30 03:54:59 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103169055 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170433 2016-03-30 04:23:04 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170433 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170642 2016-03-30 04:27:36 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170642 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170706 2016-03-30 04:28:47 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170706 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170793 2016-03-30 04:30:11 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170793 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170898 2016-03-30 04:32:01 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103170898 DUDEMAN2333 https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103171138 2016-03-30 04:36:13 UTC https://padlet.com/DUDEMAN2333/jijlvmyvw5e1/wish/103171138
