any surging or progressing movement or part resembling a wave of the sea:a wave of the pulse.

Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium —that is, with little or no associated mass transport. They consist, instead, of oscillations or vibrations around almost fixed locations.]]> 2020-04-16 04:36:19 UTC https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509863913 Transverse Waves lijeuki https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509866822 Transverse waves propagate through media with a speed  orthogonally to the direction of energy transfer.]]> 2020-04-16 04:39:32 UTC https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509866822 lijeuki https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509867291 A transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. 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. For transverse waves in matter, 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.]]> 2020-04-16 04:40:12 UTC https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509867291 Longitudinal Waves lijeuki https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509868829 Longitudinal waves, sometimes called compression waves, oscillate in the direction of propagation.]]> 2020-04-16 04:42:09 UTC https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509868829 lijeuki https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509869061 Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves. An easy experiment for observing longitudinal waves involves taking a Slinky and holding both ends. After compressing and releasing one end of the Slinky (while still holding onto the end), a pulse of more concentrated coils will travel to the end of the Slinky.]]> 2020-04-16 04:42:29 UTC https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509869061 The Frequency lijeuki https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509871309 a wave refers to how often the particles of the medium vibrate when a wave passes through the medium. ]]> 2020-04-16 04:45:23 UTC https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509871309 The period lijeuki https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509871767 a wave is the time for a particle on a medium to make one complete vibrational cycle.]]> 2020-04-16 04:45:57 UTC https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509871767 lijeuki https://padlet.com/lijeuki/anwdzugwi36lw0u6/wish/509874350 The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position.

This can be measured between two crests of a wave or two troughs of a wave.
