What is sound energy?

Back

Sound energy is a form of energy produced by vibrating sound waves that travel through a medium such as air, water, or solids.

How is energy transferred through a medium?

Back

Energy is transferred through a medium when particles collide with each other, passing the energy along the wave.

What is frequency in sound waves?

Back

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

Front

What is amplitude in sound waves?

Back

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

What happens to hair cells in response to sound?

Back

Hair cells in the inner ear vibrate in response to sound waves, converting mechanical energy into electrical signals for the brain.

Front

What is the relationship between pitch and frequency?

Back

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

Front

What is a wave peak?

Back

A wave peak is the highest point of a wave, representing the maximum displacement of the wave from its rest position.

How do sound waves travel through air?

Back

Sound waves travel through air by causing air particles to vibrate back and forth, creating areas of compression and rarefaction.

What is the difference between a low pitch and a high pitch sound?

Back

Low pitch sounds have lower frequencies and longer wavelengths, while high pitch sounds have higher frequencies and shorter wavelengths.

What is wavelength in sound waves?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave, determining the sound's frequency.
