Identify the characteristics listed that describe a Sound Wave.

• longitudinal wave

• transfers energy from one point to another

• the denser the medium, the faster the wave

• transverse wave

• travels through a vacuum

Musical instruments are designed to produce a variety of sounds by changing the size of the parts on the instrument. A xylophone uses mallets that strike the bars to make sounds; whereas a Pan Flute uses forced air through columns to produce sound.

Select the area of each instrument that will produce the lowest pitch sound that the instruments are capable of making.
