Waves: Chapter 3 Test

A student makes a model of a wave using a copper wire, as shown in the image for wave A. The student compresses the wire on each end, as shown in the image for wave B. Which properties of wave A change in wave B?

• A amplitude and frequency
• B wavelength and frequency
• C amplitude and time
• D speed and amplitude

A sound wave passes through an acoustic panel. The image shows the sound wave pressure pattern before and after interaction with the panel. What is the effect of the interaction on the sound wave?

• A The sound wave is transmitted through the panel, causing an increase in its loudness.
• B The sound wave is reflected by the panel, causing a decrease in its loudness.
• C A part of the sound is scattered, causing an increase in its pitch.
• D A part of the sound is absorbed, causing a decrease in its intensity.
