SOUND WAVES

Front

What form of energy is produced by vibrations?

Back

Sound

Front

Why does sound travel faster in solids than in gases and liquids?

Back

Solid particles are close to each other, allowing particles to move quickly in response to vibration.

Front

What happens to sound when it hits a hard, flat surface?

Back

The sound tends to bounce back, resulting in an echo.

Front

What is described as a quick movement of back and forth?

Back

Front

How does sound travel through matter and empty space?

Back

By means of sound waves.

Front

What is the term for the distance between two consecutive peaks of a sound wave?

Back

Wavelength.

Front

What is the frequency of a sound wave?

Back

The number of vibrations or cycles per second, measured in Hertz (Hz).

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves produce higher pitch sounds, while lower frequency sound waves produce lower pitch sounds.

Front

What is amplitude in the context of sound waves?

Back

The maximum extent of a vibration or oscillation, which determines the loudness of the sound.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second (m/s).
