Question 1(Multiple Choice Worth 2 points)

(03.03 LC) A sound wave is emitted underwater by a device. This device measures the reflection time. This description best illustrates

echolocation technology sonar technology refraction technology reflection technology

Question 2(Multiple Choice Worth 2 points)

(03.03 LC) Sonography captures images by using

the speed of a sound and wave reflection the reflection and refraction of the sound wave the distance between the receiver and the wave intensity the wave intensity and sound speed

Question 3(Multiple Choice Worth 2 points)

(03.03 LC) Sound waves are examples of

longitudinal waves transverse waves electromagnetic waves tension waves

Question 4(Multiple Choice Worth 2 points)

(03.03 MC) An auditorium has special panels installed along its walls and portions of the ceiling to direct sound waves. Which statement best explains the wave property these panels are taking advantage of?

Reflection, because reflected waves have a higher intensity Reflection, because reflected waves bounce off a media Absorption, because absorbed waves go into the media Absorption, because absorbed waves have a lower frequency

Question 5(Multiple Choice Worth 2 points)

(03.03 MC) In which of the following situations would sonography be most practical?

Measuring the distance between objects in the ocean Observing internal organs Determining the frequency of sounds Dampening the intensity of sounds

Question 6(Multiple Choice Worth 2 points)

(03.03 MC) The image below shows a sound wave emitted by a sound source that travels between two media. A vertical boundary exists between the two media. There are four marked locations: A, B, C, and D. Which letter identifies where the refracted wave would be after it interacts with the media boundary?

A B C D

Question 7(Multiple Choice Worth 2 points)

(03.03 LC) The refraction of a sound wave occurs when the sound wave

stops at a boundary between media bounces off the boundary between media bends as it passes through the boundary between media changes frequency after it passes through the boundary between media
