Rhythmic disturbances that carry energy without carrying matter.
What are waves?
100
the highest part of a transverse wave
What is a crest?
100
The bouncing back of an object or a wave when it hits a surface through which it cannot pass
What is a reflection?
100
your perception of the energy of a sound
What is loudness?
100
a set of notes that combine in patterns that are pleasing
What is music?
200
The type of waves that use matter to transfer energy.
What are mechanical waves?
200
the distance between crest to crest or trough to trough in a transverse wave or from compression to compression or rarefaction to rarefaction in a compressional wave.
What is a wavelength?
200
the bending of waves due to a change in speed
What is refraction?
200
unit for measuring loudness
What is a decibel?
200
this occurs when an object is made to vibrate at its natural frequencies by absorbing energy from a sound wave or another object vibrating at these frequencies.
What is resonance?
300
The parts where the coils or particles are spread out in a longitudinal or compressional wave
What is a rarefaction?
300
the number of complete waves that pass a given point in a certain amount of time
What is frequency?
300
The bending of waves as they move around a barrier or pass through an opening
What is diffraction.
300
a description of how high or low the sound seems to a person
What is pitch?
300
the lowest frequency produces by a vibrating object.
what is fundamental frequency?
400
The material through which a wave travels
What is a medium?
400
the unit of measurement for frequency
What is Hertz?
400
The interference that occurs when waves combine to make a wave with a larger amplitude
What is constructive interference?
400
a reflective sound wave
What is an echo?
400
a thin membrane that stretches across the ear canal like a drumhead.
what is the eardrum?
500
Possible answers:
Radio waves Infrared waves
Visible light waves Ultra violet waves
X-Rays Gamma Rays
What are types of electromagnetic waves?
500
a word used to describe that amount of energy a wave carries.
What is Amplitude?
500
this type of interference can reduce noise.
what is destructive interference?
500
The change in frequency of a wave as its source moves in relation to an observer
What is the doppler effect?
500
the part of the ear that is most damaged most easily by continued exposed to loud noise
