There are three types of waves: • Mechanical waves require a material medium to travel (air, water, ropes). • Electromagnetic waves do not require a medium to travel (light, radio). • Matter waves are produced by electrons and particles.
![Mechanical Waves Transverse waves cause the medium to move perpendicular to the direction Mechanical Waves • Transverse waves cause the medium to move perpendicular to the direction](https://slidetodoc.com/presentation_image/233ab011cc470520731d70e42f453c0d/image-4.jpg)
Mechanical Waves • Transverse waves cause the medium to move perpendicular to the direction of the wave. • Longitudinal waves cause the medium to move parallel to the direction of the wave. • Surface waves are both transverse waves and longitudinal waves mixed in one medium. (Such as water waves) • Torsional waves produce a twisting motion through the medium – such as the ones which caused the collapse of the Tacoma Narrows Bridge.

Waves Moving in and Out of Phase • When the 2 waves are in phase, the resulting disturbance has a maximum amplitude. • When the 2 waves are out of phase, the resulting disturbance has a minimum amplitude.

Beats • Waves of slightly different frequencies form a pattern of alternating maximum and minimum amplitude. • The packets of maximum amplitude are called beats.

Noise Canceling • tiny microphones, one on each earpiece, detect ambient noise before it gets to your ears. • noise-cancellation circuitry inverts the captured signal, turning the noise's sound wave upside down. • noise-cancellation system adds the sonic opposite of the external noise to whatever you're listening to • eliminating most of the pollution and leaving you with just your music.
