What are waves?

Rhythmic disturbances that carry energy without carrying matter.

100

What is a crest?

the highest part of a transverse wave

100
What is a reflection?
The bouncing back of an object or a wave when it hits a surface through which it cannot pass
100
What is loudness?
your perception of the energy of a sound
100
What is music?
a set of notes that combine in patterns that are pleasing
200
What are mechanical waves?
The type of waves that use matter to transfer energy.
200

What is a wavelength?

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.

200
What is refraction?
the bending of waves due to a change in speed
200
What is a decibel?
unit for measuring loudness
200
What is resonance?
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.
300
What is a rarefaction?
The parts where the coils or particles are spread out in a longitudinal or compressional wave
300

What is frequency?

the number of complete waves that pass a given point in a certain amount of time

300

What is diffraction.

The bending of waves as they move around a barrier or pass through an opening

300

What is pitch?

a description of how high or low the sound seems to a person

300
what is fundamental frequency?
the lowest frequency produces by a vibrating object.
400
What is a medium?
The material through which a wave travels
400

What is Hertz?

the unit of measurement for frequency

400
What is constructive interference?
The interference that occurs when waves combine to make a wave with a larger amplitude
400
What is an echo?
a reflective sound wave
400
what is the eardrum?
a thin membrane that stretches across the ear canal like a drumhead.
500
What are types of electromagnetic waves?
Possible answers: Radio waves Infrared waves Visible light waves Ultra violet waves X-Rays Gamma Rays
500

What is Amplitude?

a word used to describe that amount of energy a wave carries.

500
what is destructive interference?
this type of interference can reduce noise.
500
What is the doppler effect?
The change in frequency of a wave as its source moves in relation to an observer
500
what are hair cells?
the part of the ear that is most damaged most easily by continued exposed to loud noise
