Sound Waves Quiz's vocab

This is vocab.

Crest

Is the highest point on a wave.

Trough

Is the lowest point on a wave.

Wavelength

Is the distance between corresponding points of two consecutive waves.

Amplitude

Is the maximum displacement from the rest of central position.

A measure of the highest height of the wave from its rest position.

Sound

Sound is created by vibrations that cause molecules in a medium (solid, liquid, gas) to move in waves. When an object vibrates, it pushes surrounding air molecules, which bump into others, creating a chain reaction that carries the wave outward.

Frequency

How often something happens. The number of sound waves that pas a fixed point over time measured in Hertz (Hz).P

Pitch

The frequency of a sound wave. An object vibrating very fast produces a high-pitched sound. An object vibrating very slow produces a lower-pitched sound.

Compression wave

Particles move parallel to the direction of travel.<>

Transverse wave

Particles move at right angles to the direction of travel.

Medium

A substance that makes possible the transfer of energy from one location to another.(Gas, Liquid, and Solid).

Light wave

A type of wave that travels from one place to another. When these waves reflect off objects into our eyes, it enables us to see.

Lightning

The occurrence of a natural electrical charge in the sky, resulting in a bright flash to light.

Sound Wave

A type of wave that travels from one place to another. When these waves reach our ears, we hear sound.

Thunder

A loud rumbling or crashing noise resulting from the expansion of rapidly heated air due to electric discharge.

Speed of sound in air

340 m/s

Sound of light

300,000,000 m/s

sound travel fastest through …

Solid

Magnet

The non-charging magnetic field that allows the voice coil’s alternating magnetic force to be attracted or repelled.

Cone

Vibrates back and forth to create sound waves in the air.

Metal Coil

makes an electromagnet when coiled around the magnet that moves back and forth in response to the audio signal, pushing and pulling the attached speaker cone.

Wires

Move thee electrical current from the amplifier to the metal coil.Sp

Spider

A springy cloth disc that keeps the voice coil and bottom of the cone from moving off to the side and focuses the coils motion in a forward and backward motion.

Basket

Holds the entire speaker assembly together and attaches it to the cabinet.

Energy wave

A disturbance that transfers energy through a medium (like water or air) or space, without transferring matter, carrying kinetic and potential energy that can be captured

Vibrations

The repetitive, back-and-forth motion of an object or particles around an equilibrium position.

Speaker

An electroacoustic transducer that converts electrical audio signals (energy) into mechanical vibrations, which then create audible sound waves (acoustic energy) by moving air.

Electromagnetic Force

One of nature's four fundamental forces, governing interactions between electrically charged particles, causing attraction or repulsion, and manifesting as electricity, magnetism, and light.

Rest Line

An informal term for the equilibrium position (or resting position).

Echolocation

A biological sonar system where animals emit sounds (like clicks or calls) and interpret the returning echoes to navigate, hunt, and perceive their surroundings, determining an object's distance, size, shape, and location, even in darkness or murky water, using sound waves to "see".

Volume

A volume in sound refers to its loudness or quietness, which is scientifically defined as the sound's intensity or amplitude, measured in decibels (dB).

Wave speed

How fast the sound energy (the wave) moves from one point to another.

Ultrasound

Above 20,000 Hz

Infrasound

Below 20 Hz

Sonar

It sends out ultrasound waves and detects the waves after they reflect from under water objects.
