Working with the Speed of Sound

Hello, this is a new cycle for the scribes. Today in class we finished correcting the questions from last week. I will be showing the corrections later in the scribe. We also corrected the worksheet about the speed of sound that we received last week.
Okay here are the corrections for last week's work:

8a) Intensity is the energy transmitted past a given area per unit of time. It is also an objective measurement. Loudness depends on the amplitude of the wave and it is a subjective measurement.

b)Frequency is the number of vibrations per second and it is an objective measurement. While pitch is how high or low a sound is and it is a subjective measurement.

9. 20Hz to 20 000 Hz is the range of frequencies a human can hear and it is called the Audio Spectrum.

10a)529Hz - 524Hz = 5 Hz

b)t=1/f
...=1/5
...=0.2 seconds

Now here are the corrections for the worksheet about the Speed of Sound:





Okay those are all of the corrections we've done today in our Physics class. Homework for tomorrow is the worksheet that we received called Sound Waves. Our next scribe will be... ERICT. So until next time good luck in school and hope this helps. Bye Bye.
