8.2 Sound Waves Lesson 1-6 Flashcard

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that is created by vibrating objects and travels through a medium (like air, water, or solids) as a series of compressions and rarefactions.

Front

What determines the loudness of a sound?

Back

The loudness of a sound is determined by its amplitude; larger amplitudes produce louder sounds.

Front

What determines the pitch of a sound?

Back

The pitch of a sound is determined by its frequency; higher frequencies produce higher pitches.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

How is sound produced on a guitar?

Back

Sound is produced on a guitar when the strings vibrate, creating sound waves that travel through the air.

Front

What is the relationship between frequency and time for a vibrating object?

Back

If a sound source vibrates at a frequency of 2 waves per 2 seconds, it completes 1 cycle (back and forth) every second.

Front

What is the role of the strings on a guitar?

Back

The strings are the primary sound sources on a guitar; they vibrate to produce sound when plucked or strummed.

Front

What is a motion detector?

Back

A motion detector is a device that measures the movement of an object, often used to analyze sound waves by tracking their source.

Front

What is amplitude?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium; it relates to the loudness of the sound.

Front

What is a compression in a sound wave?

Back

A compression is a region in a sound wave where the particles of the medium are close together, resulting in higher pressure.
