Sound Waves Quiz

Energy Wave

the transfer of energy through a medium or space via oscillations, without transferring matter itself

Sound

energy that travels in waves, created by vibrations that disturb matter (like air, water, or solids) and travel outward from a source

Vibrations

the rapid, repetitive back-and-forth or oscillating motion of an object or system around a central equilibrium point

Speaker

a person who presents scientific ideas (like a guest lecturer) or, more commonly, a device that converts electrical signals into sound using electromagnetism, physics, and vibrations to create audible sound waves

Electromagnetic Force

uniting electricity and magnetism, governing interactions between charged particles (attraction/repulsion), holding atoms and molecules together, responsible for light, and enabling technologies

Crest

the highest point of a wave, such as a water wave, sound wave, or light wave

Trough

the lowest point or valley in a wave (like ocean waves, sound, or light), a long, shallow depression (like in geology or meteorology), or a low-pressure area in weather, representing a dip in a periodic function or physical feature

Wavelength

the distance between two identical points on a wave, like from crest to crest or trough to trough, representing the spatial period of the wave

Amplitude

the maximum extent of a vibration or oscillation, measured as the distance from the position of equilibrium

Frequency

the number of times a repeating event, such as a wave or oscillation, occurs per unit of time

Rest line

undisturbed line through which a wave oscillates. 

Pitch

how high or low a sound is perceived, directly determined by the frequency (vibrations per second) of its sound waves

Echolocation

the location of objects by reflected sound, in particular that used by animals such as dolphins and bats.

Volume

the perceived loudness or softness of a sound

Compression Wave

a disturbance where particles in a medium (like air) oscillate back and forth parallel to the wave's direction, creating alternating regions of high pressure (compressions) where particles bunch up, and low pressure (rarefactions) where they spread out

Wave speed

how fast a wave disturbance travels through a medium (like water, air, or a string) or a vacuum, measured as distance per time (e.g., meters per second)

Medium

the substance or material (solid, liquid, gas, or even vacuum) that carries or transmits energy, waves (like sound, light), or signals from one point to another

Thunder

the powerful sound created by the extreme, rapid heating and expansion of air by a lightning discharge
