A student lab group is brainstorming the design of an experiment in which they wish to determine how the frequency at which you shake a Slinky would affect the wavelength. Which of the following describes the most effective design? 1. Shake Slinky with frequency of 1.0 Hz. Measure the wavelength and the speed. Record data in notebook. Use a different speed and shake once more at 1.0 Hz. Measure and record the wavelength. Continue changing the wave speed while keeping frequency constant. Measure and record the wavelength for each trial.
A student lab group is brainstorming the design of an
experiment in which they wish to determine how the
frequency at which you shake a Slinky would affect
the wavelength. Which of the following describes the
most effective design?
1. Shake Slinky with frequency of 1.0 Hz. Measure
the wavelength and the speed. Record data in
notebook. Use a different speed and shake once
more at 1.0 Hz. Measure and record the
wavelength. Continue changing the wave speed
while keeping frequency constant. Measure and
record the wavelength for each trial.
2. Shake Slinky with frequency of 1.0 Hz. Measure
and record the wavelength. Shake Slinky at 2.0
Hz. Measure the wavelength. Repeat this
procedure for 3.0 Hz, 4.0 Hz, and 5.0 Hz.
Measure and record wavelength for each
frequency.
3. Shake Slinky with frequency of 1.0 Hz. Then
shake the Slinky with frequency of 2.0 Hz. Then
shake with a frequencies of 3.0 Hz, 4.0 Hz, and
5.0 Hz. Record data for each frequency.
4. Shake Slinky with frequency of 1.0 Hz. Measure
and record the wavelength. Get a new Slinky and
repeat the trial with a frequency of 1.0 Hz. Repeat
for several different Slinkies, being careful to keep
the frequency controlled at 1.0 Hz and measuring
the wavelength in each trial.
