What does pitch depend on?
Pitch depends on the frequency of the wave
What is the unit of measurement of frequency?
Hz
What is loudness?
Loudness describes your awareness of the energy of a sound
What does loudness depend on?
Loudness depends on the energy, amplitude, and intensity
How does energy affect loudness?
The more energy, the louder the sound
How does intensity affect loudness?
The greater the intensity, the louder the sound.
How do you measure loudness?
You measure loudness using decibels.
What is the doppler effect?
The doppler effect is the change in frequency of a wave as the source moves in relation to the observer
Why does the doppler effect occur?
It occurs because the motion of the object/source causes it to spread apart or get closer.
