You can say, "My best friend and I are on the same wavelength,"meaning you truly understand each other and tend to see the world in the same way. This meaning has been around since the 1920s, but originally wavelength had only its scientific definition, "the distance between two peaks of a wave."]]> 2017-11-14 23:28:48 UTC https://padlet.com/3044941/6hsi4xsffp7i/wish/207004564 3044941 https://padlet.com/3044941/6hsi4xsffp7i/wish/207005157 Definition of amplitude. 1 :the extent or range of a quality, property, process, or phenomenon: such as. a :the extent of a vibratory movement (as of a pendulum) measured from the mean position to an extreme. b :the maximum departure of the value of an alternating current or wave from the average value.]]> 2017-11-14 23:32:57 UTC https://padlet.com/3044941/6hsi4xsffp7i/wish/207005157 3044941 https://padlet.com/3044941/6hsi4xsffp7i/wish/207005282 Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion. ...
