Physics P1 5.7 Musical sounds.

HideShow resource information
When does the pitch of a note increase?
If the frequency of the sound waves increases.
1 of 14
What does the loudness of a note depend on?
The amplitude of the sound waves.
2 of 14
What do the vibrations created in an instrument produce when it is played?
Sound waves.
3 of 14
The higher the frequency of sound waves the higher...?
The pitch of a note.
4 of 14
What does the loudness of a sound depends on?
The amplitude of the sound waves.
5 of 14
The greater the amplitude the more...?
Energy the wave carries and the louder the sound.
6 of 14
What do tuning forks and signal generators produce?
'Pure' waveforms.
7 of 14
What does the quality of a note depend on?
The waveform.
8 of 14
Why do different instruments sound different from each other?
Different instruments produce different waveforms.
9 of 14
What produces sound waves when an instrument is played?
Vibrations created in the instrument.
10 of 14
What are the different ways in which vibrations in an instrument create sound waves?
In some instruments, such as a saxophone, a column of air vibrates; in others, such as violin, a string vibrates; in others, such as a xylophone, instruments vibrate when they are struck.
11 of 14
What happens to the pitch of a note as the frequency decreases?
The pitch decreases.
12 of 14
Why do different instruments sound different when they play the same note?
The waveforms are different.

**PRACTICE SKETCHING WAVEFORMS, E.G. A WAVE WITH TWICE THE FREQUENCY AND HALF THE AMPLITUDE OF THE ORIGINAL**
**LOOK UP SKETCHES OF WAVEFORMS AND DIFFERENT SOUNDS***
