Front

What happens in the inner ear?

Back

Sound waves are converted into nerve impulses in the inner ear.

Front

What is amplitude?

Back

Amplitude is the height of a sound wave, which determines its loudness.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks of a sound wave.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one 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 waves produce lower pitch sounds.

Front

What is a sound wave?

Back

A sound wave is a longitudinal wave that is created by vibrating objects and travels through a medium.

Front

What is the medium in sound transmission?

Back

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