While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.]]> 2017-11-14 17:27:24 UTC https://padlet.com/304971/sq01xe0n5puw/wish/206850875 304971 https://padlet.com/304971/sq01xe0n5puw/wish/206851077 A wave vibrating at right angles to the direction of its propagation.]]> 2017-11-14 17:27:42 UTC https://padlet.com/304971/sq01xe0n5puw/wish/206851077 304971 https://padlet.com/304971/sq01xe0n5puw/wish/206851582 The change in direction of a wave, such as a light or sound wave, away from a boundary the wave encounters.Reflected waves remain in their original medium rather than entering the medium they encounter.]]> 2017-11-14 17:28:31 UTC https://padlet.com/304971/sq01xe0n5puw/wish/206851582 304971 https://padlet.com/304971/sq01xe0n5puw/wish/206851640 Refraction is the change in direction of wave propagation due to a change in its transmission medium.
