|
How is sound produced? Tuning forks in water.

|
|
| T |
The number of vibrations (waves) in a bit of time is known as the frequency of a wave. |
|
What is the frequency of a wave? |
|
|
| T |
Frequency is measured in hertz (Hz) which means number per second. |
|
What unit is frequency measured in? |
|
|
| W |
The higher the frequency of sound, the higher the pitch. |
|
What is the relationship between frequency and the sound produced? http://onlinetonegenerator.com/hearingtest.html |
|
|
| T |
An oscilloscope can be used to view the the very fast changing signals produced by a microphone or signal generator. |

|
| W |
The closer the peaks on an oscilloscope the higher the frequency of the signal and therefore the wave. |
|
What does a high frequency signal look like on an oscilloscope, compared to a low frequency signal? |
|
|
| T |
The taller the peaks on an oscilloscope the higher the amplitude of the signal and therefore wave. |
|
What does a high amplitude signal look like on an oscilloscope, compared to a low amplitude signal? |
|
|
| W |
The higher the amplitude of the wave, the more energy in the wave and therefore the louder the sound. |
|
What is the relationship between energy and amplitude? |
|
|
| A |
Students can describe both the wave and the sound from a oscilloscope trace. |
