Test Name: SCI.PS - Unit 3 - Waves (Systemwide)

A stretched spring attached to two fixed points is compressed on one end and released, as shown below.

The resulting wave travels back and forth between the two fixed ends of the spring until it comes to a stop. This mechanical wave is an example of a -

• transverse wave
• longitudinal wave
• superpositioned wave
• refracted wave

A student uses a sensor to graph the sound waves produced as she sings into a microphone for five seconds. How will the graph indicate a change in the volume of her voice?

• The wavelength will increase with lower volumes.
• The compressions become closer with higher volumes.
• The amplitude will increase with higher volumes.
• The frequency decreases with lower volumes.

Helen attends a musical concert held in an auditorium. Although speakers are spaced evenly around the auditorium, the sound is much louder at some spots than others. Which property of waves most likely explains this variation in loudness?

• Absorption
• Diffraction
• Interference
