Characteristics of Waves

echo

A bound sound wave is called a(n)

Sound wave

A longitudinal wave that is caused by vibrations and is carried through a medium is a(n)

noise

A non musical sound that includes a random mix of pitches

sonic boom

An extremely fast airplane can cause an explosive sound called a(n)

standing wave

In a(n) ________, some portions of the wave are at rest while other portions have a large amplitude.

Medium

Most waves travel through some kind of material called a

Water wave

Waves are rhythmic disturbances. The easiest type of wave to visualize is a

reflection

When any kind of wave bounces off a barrier, the bouncing back of the wave is called

transverse waves

You can produce ______ waves in a rope by snapping it up and down.

Hertz

The frequency of the wave is expressed in units called

ear drum

The hammer, anvil, and stirrup bones are in the

Crests

The highest points of such waves are called _____

Constructive interference

The sound compressions overlap to produce a louder sound.

velocity

The speed at which the wave crests move is the _____.

Troughs

The west points of such waves are called _____

Compression Waves

Travel by Rarefaction and Compression. Travel with speed affected by the medium [Type (solid, liquid, and gas), temperature. Have wavelength, frequency (which causes us to hear pitch (Hz)), amplitude/intensity (which causes us to hear Loudness (dB))

Constructive or destructive interference

occurs when sound waves overlap and combine.

Destructive interference

The compressions and rarefactions combine to cancel the sound waves

Wavelength

The distance between the high point of one wave and the high point of the next wave is the ______

Amplitude

The distance from the crest of a wave to the rest position of the medium is the _______ of the wave.

Frequency/Pitch

The extent to which a note can be heard determines its ______, and the _______ is how low or high the note sounds.

medium

A physical environment in which phenomena occur is a(n)

Decibels

A unit to express loudness of a sound is

Wavelength

Compression Waves have

amplitude/intensity

Compression Waves have _______ which causes us to hear Loudness (dB)

Frequency

Compression Waves have ________which causes us to hear Pitch (Hz).

Loudness (dB)

Compression Waves have amplitude/intensity which causes us to hear

Pitch (Hz)

Compression Waves have frequency which causes us to hear

Rarefaction [and] Compression

Compression Waves travel by

Medium

Compression Waves travel with speed affected by the

Resonance

Due to _____, the vibration of a turning fork can cause a guitar string to vibrate when the fork is held near the string.

sound quality

Each instrument has a unique _______ that is the result of several pitches blending together through interference.

echolocation

Reflected sound waves are the basis for ______, a method whales and bats use to find food.

Doppler effect

The apparent change in the pitch of a car's horn as it moves past you is a result of the

Frequency

The number of wave crests that pass a place in one second is called the ______ of the wave

outer ear

The part of the ear that collects sound waves is the

Medium

This material can be a solid, liquid, or gas.

inner ear

Vibrations are changed into electrical signals in the

Type (solid, liquid, and gas) [and] temperature

different kinds of medium

Interference

is the ability of two or more waves to combine and form a new wave.

Reverberation

is the echo effect produced by multiple reflections of sound.

Resonance

is the tendency of an object to vibrate at the SAME frequency as another vibrating source. It is also the cause of sound production in musical instruments.

Earthquakes

transfer energy in powerful shock waves that travel through Earth.
