100 POINTS! please help!!!
will mark brainlist too!

please look at attachment for data.

1. Calculate the speeds of waves 1, 2, and 3 and record these values in Table 1.
Average the speeds of these three waves to determine the speed of the wave in the spring or rope you are using.


2. Calculate the frequencies of waves 4, 5, and 6 and record these values in Table 2.
3. Multiply the frequency of each wave in Table 2 by its wavelength. Compare this calculated value to the speed of the wave. What do you notice?

4. Analyze the values for frequency and wavelength in Table 2. Describe the proportionality that exists between these two variables. Explain.

5. Based on your calculations, what would you suggest is the equation that relates the speed, frequency, and wavelength of a wave?

6. If you used, or were to have used, a different spring or rope to re-do the procedure, would the
a) measurements have been the same? Explain.
b) relationship between the three variables have been the same? Explain.

2. Identify some possible causes of uncertainty in this investigation. What effects could this have on your calculations? Estimate how large those effects might be.
