Waves

QuestionAnswer
Wave A traveling disturbance that carries energy from one place to another
Sound wave Any vibration or disturbance can be a source
Medium The substance that the wave travels through, it can be a solid liquid or gas
Energy moves, matter doesn't The energy of a wave moves from the source outward, the master itself does not travel with the wave
Transverse waves The particles of the medium vibrate perpendicular ( at a right angle ) to the direction the wave is traveling
Crest The highest point of the wave above is resting position
Trough The lowest point of the wave below is resting position
Longitudinal waves The particles of the medium vibrate parallel ( in the same direction ) to the direction the wave is traveling
Compression the part of a longitudinal wave where the particles of the medium are crowded close together
Rarefaction The part where the particles are spread apart
Mechanical waves Waves that require a medium ( solid liquid gas ) to travel
Mechanical waves They need particles of matter to physically bump into eachother to carry energy from one place to another
Mechanical waves Sounds waves ( longitudinal ) need store or another material to travel. Waves on a rope ( transverse ) need a rope
Mechanical waves They can be either longitudinal or transverse
Electromagnetic waves Electromagnetic waves are made of electric energy and magnetic energy vibrating together
Electromagnetic waves They are part of the electromagnetic spectrum
Electromagnetic waves Waves that do not require a medium. They don't need particles to bump into eachother
Electromagnetic waves Light is an electromagnetic wave. Light from the sun travels through the empty space of the solar system to reach the earth
