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 18:32:08 UTC https://padlet.com/305158/kr1ar82enj7s/wish/206890336 305158 https://padlet.com/305158/kr1ar82enj7s/wish/206891840 a wave vibrating at right angles to the direction of its propagation.]]> 2017-11-14 18:34:29 UTC https://padlet.com/305158/kr1ar82enj7s/wish/206891840 305158 https://padlet.com/305158/kr1ar82enj7s/wish/206893707 the middle quality or state between two extremes; a reasonable balance.]]> 2017-11-14 18:37:34 UTC https://padlet.com/305158/kr1ar82enj7s/wish/206893707 305158 https://padlet.com/305158/kr1ar82enj7s/wish/206895383 It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle. In classicalphysics, the diffraction phenomenon is described as the interference of waves according to the Huygens–Fresnel principle.

Common examples include the reflectionof light, sound and water waves.

For example, waves in deep water travel faster than in shallow.
