8th Grade Sound wave

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (like air, water, or solids) as a vibration of particles.

Front

What is amplitude in a sound wave?

Back

Amplitude is the height of the wave from its rest position, which determines the loudness of the sound.

Front

What happens to the pitch of a sound as the frequency increases?

Back

As the frequency increases, the pitch of the sound also increases.

Front

What is frequency in the context of sound waves?

Back

Frequency is the number of waves produced in one second, measured in Hertz (Hz).

Front

What is the relationship between amplitude and loudness?

Back

Higher amplitude means a louder sound, while lower amplitude means a softer sound.

Front

What do we call the highest point of a wave?

Back

The highest point of a wave is called the crest.

Front

What do we call the lowest point of a wave?

Back

The lowest point of a wave is called the trough.

Front

What is wavelength in a sound wave?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

How does temperature affect the speed of sound?

Back

As temperature increases, the speed of sound also increases because particles move faster.

Front

What is the unit of measurement for frequency?

Back

The unit of measurement for frequency is Hertz (Hz).
