# Science Waves

Wave A disturbance that transfers energy from place to place
Energy The ability to do work.
Medium A material through which a wave travels.
Mechanical Wave A wave that only travels through a medium.
vibration A repeated back and forth or up and down movement.
Transverse Wave Waves that move a right angles of the rest line.
Crest The high part of a transverse wave.
Trough The low part of a transverse wave.
Longitudinal Wave A wave in which the medium moves parrallel to the rest line.
Compression The part of a longitudinal wave when the molecules are close together.
Rarefaction The part of a longitudinal wave when the molecules ar far apart.
Amplitude The distance from the rest line a crest or trough goes.
Wavelength The distance between to corresponding parts of the wave.
Frequency The number of time a wave passes in a given number of seconds.
Hertz The amount of wavelenghts that pass in one second.
Reflection When a object or wave hits a surface where it cannot pass through, but come back
Law of Reflection The angle of incidence= the angle of reflection
Refraction The bending of waves due to change in speed.
Diffration When a wave bends around or through a barrier and spreads out.
Interference The interaction between two waves that meet.
Constructive Interference When two waves combine to make a higher amplitude.
Destructive Interference When two waves combine to make a smaller amplitude.
Standing Wave A wave that appears to stand in one place when it is two waves passing each other.
Node Points of zero amplitude on a node.
Antinode The points of maximum amplitude on a node.
Resonance An increase in the amplitude of vibration that occurs when external frequencies match the natural frequency.
Echo Sound Waves that reflect when they hit a surface.
Elasticity The ability of an object to bounce back after being disturbed.
Density The amount of matter, or mass in a given space, or volume.
Loudness The perception of energy in a sound.
Intensity The amount of energy a sound carries per second through a unit area.
Decibel The unit for measuring loudness
Pitch The sound how high or low a person percieves of the sound.
Ultrasound Sound waves that have frequincies above the range of the human ear.
Infrasound Sound waves that have frequencies below the range of the human ea
Larynx The part of the throat that produces noise.
Doppler Effect The change in frequencies due to the postion of the observer.
Music A set of notes that when combined are pleasing.
Fundamental Tone The lowest natural frequency of an object.
Overtone The object's higher natural frquency of an object.
Acoustics The study of how sound reacts with the enviornment.
Reverberation The echoes of a sound of heard after the sound of the source stops.
Ear Canal Collects sound waves.
Eardrum A drumlike membrane that vibrates when it hears sound waves.
Cochlea A fluid cavity shaped like a conch shell.
Echolocation The reflection of sound waves to determine the distance of objects.
Sonar Using sound waves the create a picture of objects.
Sonogram Using ultrasound to make a picture.
Formula for Frequency frequency=speed - wavelength
Formula for Wavelenght Wavelenght= speed ----- frequency
Formula for Speed Speed=Frequency x wavelength
