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

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

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

What is an echo?
a reflective sound wave
400
