Experiment #1Aim:
To determine how the wavelength (frequency) of sound affects its refraction through a Carbon Dioxide balloon.
Hypothesis:

MethodA consistent setup was used to gather all the results which were
collected by a microphone connected to a computer-generated Oscilloscope.

Discussion• The hypothesis was at first glance supported by the results
• The higher frequencies created a higher amplitude than the lower ones when refracted with the CO2 balloon.

The focal length was inside the balloon
The loudest point is right next to the
balloon.

Discussion• The Carbon Dioxide balloon was a biconvex lens and
refracted the sound inwards.
• Improvements…

Experiment #2Aim:
To determine how the refraction of sound with a Carbon Dioxide balloon is affected by the size of the balloon.
Hypothesis:
• It was determined from the results that the size had very little affect upon the level of refraction, the shape was more relevant.

Conclusion• In Summary
• The hypothesis for the first experiment was not supported but it was determined to be the opposite
• The hypothesis for the second experiment was not supported at all
