Question 1
why do we calculate the "average" of the measurements?
because every measurement has some error in it, and the "average" has less error.
because we don't know which measurement is the correct measurement.
question 2
why do we calculate the "range" of the measurments?
to get an ballpark idea of how much "error" is in the "average" measurement
to set upper and lower error limits on the y-value of each x-y data pair
to show if a straight "trend line" represents the experimental data
all of the above
question 3
which variable goes on the x-axis?
the controlled variable
the independent variable (manipulated variable)
the depenedent variable (responding variable)
question 4
which variable goes on the y-axis?
the controlled variable
the independent variable (manipulated variable)
the dependent variable (responding variable)

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
