love waves

energy

the ability to do work or cause change

inverse relationship

a mathematical relationship where if one variable increases, the other decreases

mechanical wave

a wave that can only travel through a medium

medium

a substance or material (solid, liquid, or gas)

variable

any factor that can be changed

oscillation

a regular pattern of motion

tsunami

a high energy ocean wave created by an underwater disturbance

constraint

a factor that limits what can be done

prototype

a physical or digital model of a new design

vibration

a quick back-and-forth motion

property

something you can observe about an object, material, or system

volume

how loud a sound is, which depends on the amplitude of its sound wave

pitch

the highness or lowness of sound, which depends on the frequency of its sound wave

decibel (dB)

a unit used to measure the amplitude of sound

absorb

to take in or soak up

echo

the reflection of a sound off a distant surface

reverberation

the collection of closely spaced sound reflections off many surfaces

noise

a disturbance that reduces the quality of a signal

acoustics

the study of sound

amplitude

the height of the peaks above the resting line in a wave

frequency

a rate of a repeating event

reflection

the bouncing back of waves off an object

research

looking for work that may have already been done

brainstorm

a process in which people freely make up creative ideas

criterion

a requirement that must be met
