Unit 2 Lessons 1-6 Soundwaves

Front

What do all waves have in common?

Back

All waves transfer energy.

Front

What happens when you change the amplitude of a sound wave?

Back

Changing the amplitude of a sound wave changes its loudness.

Front

How does pressing a piano key harder affect the sound wave?

Back

Pressing the key down harder increases the sound wave's amplitude and energy.

Front

When the frequency of a wave decreases, what happens to the wavelength?

Back

When the frequency of a wave decreases, the wavelength increases.

Front

How do sound waves travel through different mediums?

Back

Sound waves travel faster through liquids than through gases.

Front

What is the definition of a sound wave?

Back

A sound wave is a type of mechanical wave that propagates through a medium (solid, liquid, or gas) by vibrating particles.

Front

What is amplitude in the context of sound waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium, and it determines the loudness of the sound.

Front

What is frequency in sound waves?

Back

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

Front

What is wavelength in sound waves?

Back

Wavelength is the distance between successive crests (or troughs) of a wave, and it is inversely related to frequency.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.
