Stnd 06: Properties of Waves
To play high pitch notes on a guitar, a
musician must decrease the length of the strings by pressing down on the strings with his or her
fingers as they are being plucked or strummed. Now
imagine that a guitar string is cut into four pieces of different lengths as shown below. Each
piece is stretched between two supports to the same tightness.
If each piece was plucked in
the middle with the exact same amount of force, which of the pieces would have the highest number of
wave oscillations during one second?

Stnd 06: Properties of Waves
If you press down on a piano key,
let's say middle C, it generates a sound wave. Now, imagine that you press it down much harder
so that it still plays the same tone but more loudly. How would pressing the key down harder change the sound wave
produced?
a. | The sound wave's wavelength would increase. | b. | The sound
wave's energy would decrease. | c. | The sound wave's amplitude would be
larger. | d. | The sound wave's frequency would increase. |

A ray of light shines
through a transparent window. Next it shines through a transparent glass cup containing water and a
straw in it. You notice that the straw in the water appears to be misshaped. The light shining
through the glass next impacts a mirror on the far side of the room. Diagram 01 | Diagram 02 | Diagram 03 | Diagram 04 | | | | | | | | |
