Sound

What is sound?

Back

Sound is a type of energy that travels through the air (or other mediums) as waves, created by vibrations.

Front

How does sound travel through different mediums?

Back

Sound can travel through solids, liquids, and gases, but it travels fastest in solids due to closer particle arrangement.

Front

What is the primary cause of sound?

Back

Sound is primarily caused by vibrations of objects.

Front

What is a vibration?

Back

A vibration is a back-and-forth movement of matter.

Front

Can sound travel through a vacuum?

Back

No, sound cannot travel through a vacuum because there are no particles to transmit the sound waves.

Front

What is the role of the eardrum in hearing?

Back

The eardrum vibrates in response to sound waves, converting them into mechanical vibrations that are transmitted to the inner ear.

Front

What are sound waves?

Back

Sound waves are longitudinal waves that consist of compressions and rarefactions of particles in a medium.

Front

What is frequency in relation to sound?

Back

Frequency refers to the number of waves that pass a point in one second, measured in Hertz (Hz), and determines the pitch of the sound.

Front

What is amplitude in sound waves?

Back

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

Front

What is the difference between pitch and loudness?

Back

Pitch is determined by the frequency of the sound wave, while loudness is determined by the amplitude of the sound wave.
