Oscillating Spring Lab

the purpose of this lab was to show the relationship between the period of the wavelength and the period and thus the frequency.
we used a meter stick to measure the length of the wave and made one wave, meaning we would have to take 2L to get the fun wave length 
we took 4 sets of data each has five points

                                                             wavelength
3m                                    4m                                                 4.6m                              3m
                                                            time (10 oscillations)      

6.01                               8.09                                              9.53                               10.19
6.18                               7.88                                              9.59                                9.96
6.38                               7.86                                              9.45                                9.43
6.03                               7.88                                              9.42                               10.02
6.22                               7.80                                              9.52                               10.05


from these time we can find the period of the oscillating wave
3m             .616s
4m             .7912s
4.6m          .949s
6m             .9935s

analysis
from this we can conclude that the longer wave length well indeed give you a longer period, meaning the frequency of your wave would inversely proportional to the wavelength.
from this lab experiment we have essentially proven the equation
                                                               v=f lamda
