Question

Question 1: During the lab we will be measuring the sound waves produced by tuning forks. The data of sound pressure with respect to time we will look similar to the graph below. Use the graph to answer the following questions. This question is the same as the online quiz question 5. You will get two attempts on this quiz, if you get your first attempt incorrect please adjust your method Sound Pressure vs. Time 01 0.0 0.1 0.00 0.01 0.02 0.03 Time (s) (2pts) Frequency is how many times a wave repeats itself over 1 s. The graph above shows a sound wave, measured by sound pressure, graphed as a function of time. How can you use the data shown in the graph above to find the frequency,f, of this sound wave? Describe the method that you could use to find the frequency of the sound wave in the graph above. You will test this method in the next step. a. b. (lpt) Use your method to determine the frequency of the sound wave in the figure above.

Explanation / Answer

a) In .001 s wave is repeating In 1 s it will repeat 1÷0.001 = 1000 times

Hence frequency = 1000 Hz

b) frequency = 1/Time Period =1/0.001 = 1000 Hz
