Question

question 3 (multiple choice worth 2 points) (03 03r 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 4 (multiple choice worth 2 points) (03 03r lc)

Explanation:

Sonar (Sound Navigation and Ranging) uses sound - waves emitted underwater and measures the time of reflection to detect objects or map the underwater environment. Echolocation is similar but is more commonly associated with animals. Refraction involves the bending of waves, not just reflection. The description clearly fits sonar technology.

Answer:

B. sonar technology
