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. Mechanical waves transport energy.]]> 2017-02-17 18:22:37 UTC https://padlet.com/mendozanayzethe/mechanicalwaves/wish/154664956 mendozanayzethe https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156498583 The pitch of a sound is how you hear and interpret its frequency. A low-frequency sound has a low pitch, like a rumble of a big truck or a bass guitar. A high-frequency sound has a high pitch, like the sound of a whistle or siren. Human can hear frequencies between 20 Hz and 20,000 Hz.]]> 2017-02-27 17:49:05 UTC https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156498583 mendozanayzethe https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156507882 Lightning is what creates thunder so they really happen at the same time. You hear a delay because sound travels much slower than light. The speed of sound is about 1,000 km/h (660 mph). Light travels at 300,000 km/s (186,000 mi/s). Sound travels through most liquids and solids faster than through air. Sound travels about 5 times faster in water]]> 2017-02-27 18:13:56 UTC https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156507882 mendozanayzethe https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156892340 2017-02-28 23:30:18 UTC https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156892340 mendozanayzethe https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156892778 Three types of mechanical waves are transverse, longitudinal, & surface waves. Mechanical waves require a material medium to travel. Three types of mechanical waves are transverse, longitudinal, & surface waves. Mechanical waves require a material medium to travel.

If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. Light is an example of a transverse wave.]]> 2017-02-28 23:40:39 UTC https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156893206 mendozanayzethe https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156893380 Longitudinal waves, also known as "l waves", are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of travel of the wave. Mechanical longitudinal waves are also called congressional waves or compression waves, because they produce compression and rarefaction when traveling through a medium.]]> 2017-02-28 23:42:32 UTC https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156893380 mendozanayzethe https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156893828 A surface wave is a mechanical wave that propagates along the interface between differing media, usually as a gravity wave between two fluids with different densities. A surface wave can also be an elastic (or a seismic) wave, such as with a Rayleigh or Love wave. It can also be an electromagnetic wave guided by a refractive index gradient.]]> 2017-02-28 23:47:48 UTC https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156893828 mendozanayzethe https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156894123 2017-02-28 23:50:42 UTC https://padlet.com/mendozanayzethe/mechanicalwaves/wish/156894123
