Analyzing Graphs of Sound Source Vibrations

Based on the graphs, which claim about Graph A supports the instance that sound was made by hitting a xylophone?

• Graph A: the sound that was made was a middle pitch note because there are a medium number of vibrations in the time period.

• Graph A: the xylophone that made the sound in Graph A is the highest pitch sound because it has the most vibrations.

• Graph A: the xylophone that made the sound in Graph A is the lowest pitch sound because it has the least number of vibrations.

• Graph A: the xylophone that made the sound in Graph A is the highest pitch sound because it has the least amount of vibrations.

Based on the graphs, which claim about Graph B supports the instance that sound was made by hitting a xylophone?

• Graph B: the sound that was made was a middle pitch note because there are a medium number of vibrations in the time period.

• Graph B: the xylophone that made the sound in Graph B is the highest pitch sound because it has the most vibrations.

• Graph B: the xylophone that made the sound in Graph B is the lowest pitch sound because it has the least number of vibrations.

• Graph B: the xylophone that made the sound in Graph B is the highest pitch sound because it has the least amount of vibrations.

Based on the graphs, which claim about Graph C supports the instance that sound was made by hitting a xylophone?

• Graph C: the sound that was made was a middle pitch note because there are a medium number of vibrations in the time period.

• Graph C: the xylophone that made the sound in Graph C is the highest pitch sound because it has the most vibrations.

• Graph C: the xylophone that made the sound in Graph C is the lowest pitch sound because it has the least number of vibrations.

• Graph C: the xylophone that made the sound in Graph C is the highest pitch sound because it has the least amount of vibrations.
