A mnemonic would be to remember that LONGitudinal waves are LONG, not wavy. ]]> 2017-04-21 00:33:08 UTC https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167396784 Space noah_wingate https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167397028 Sound waves move through air or other materials.

Refraction is when waves, are deflected when the waves go through a substance. The wave generally changes the angle of its general direction.

Diffraction is a characteristic of waves of all types. We can hear around a corner because of the diffraction of sound waves. ]]> 2017-04-21 00:44:37 UTC https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167397933 Loud or Soft? noah_wingate https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167401917 A larger amplitude means a louder sound, and a smaller amplitude means a softer sound]]> 2017-04-21 01:31:42 UTC https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167401917 Primary Colors of Light noah_wingate https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167402076 The primary colors of light differ from paint. They make white when combined, not dirty brown. ]]> 2017-04-21 01:33:30 UTC https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167402076 Pitch noah_wingate https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167402203 A higher frequency sound has a higher pitch, and a lower frequency sound has a lower pitch]]> 2017-04-21 01:35:07 UTC https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167402203 Harmonics noah_wingate https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167402440 Consonance is a pleasant set of pitches while a dissonance is an unpleasant one. ]]> 2017-04-21 01:37:53 UTC https://padlet.com/noah_wingate/qwjmfsqe588v/wish/167402440
