What is sound?

Back

Sound is a type of energy that travels in waves and is produced by vibrating objects.

Front

What is frequency in sound waves?

Back

Frequency is the number of vibrations or cycles per second in a sound wave, measured in Hertz (Hz).

Front

How does frequency affect pitch?

Back

Higher frequency results in higher pitch, while lower frequency results in lower pitch.

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the sound wave, which determines the loudness of the sound.

Front

What is the speed of sound in air?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What is a medium in the context of sound?

Back

A medium is a substance (solid, liquid, or gas) through which sound waves travel.

Front

Why does sound travel faster in solids than in gases?

Back

Sound travels faster in solids because the particles are closer together, allowing vibrations to transfer more quickly.

Front

What is an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay.

Front

What is the difference between longitudinal and transverse waves?

Back

Longitudinal waves have particle movement parallel to the wave direction, while transverse waves have particle movement perpendicular to the wave direction.

Front

What is pitch?

Back

Pitch is how the human ear interprets the frequency of a sound wave.
