Surveyor's wheel conversions 08:00: 266 ft × 12 in/ft × 2.54 in/cm × 1 m/100 cm = 81.1 m 11:00: 260 ft × 12 in/ft × 2.54 in/cm × 1 m/100 cm = 79.2 m
[c] The conclusion should include a discussion of the wave shapes, frequencies, wavelength and their relationship to pitch, characteristics of the sound/instrument. Discussion can also include the range over which we could hear sounds.
Note for next term: do not forget the ukele. Find other musical instruments. Invite students to bring an instrument.
