A glass breaks when the frequency of a singer’s voice is the same as the natural frequency of the glass. This is an example of what wave phenomenon?

• absorption

• reflection

• refraction

• resonance

When the guitar string is plucked and the tuning peg is turned, adjusting the tension on the string, what happens to the sound of the guitar?

• The sound changes speed.

• The sound changes amplitude.

• The sound changes volume.

• The sound changes pitch.

A student builds a marimba with different-sized metal pipes and wooden blocks. Different notes on the marimba are represented by the letters A-G. The student hits a block with a mallet and produces a note, which resonates in the pipe. How can the student produce notes at a lower pitch on the marimba?

• The student can use longer pipes.

• The student can use shorter pipes.

• The student can hit the blocks with less force.

• The student can hit the blocks with more force.

When a rope is moved up and down between two people, a wave is formed. The up and down movement of the rope from person to person is most likely used to model how energy is

• always conserved.

• converted by gravity.

• lost to the environment.

• transferred through a medium.
