Sonar Technology

What are the two main types of sonar systems?

• Active sonar and passive sonar

• Active sonar and active sonar

• Passive sonar and radar

• Echo sonar and visual sonar

Name one application of sonar technology in marine navigation.

• Wave prediction

• Depth measurement and obstacle detection

• Temperature measurement

• Fish tracking

What is one advantage of using sonar technology in underwater exploration?

• Ability to communicate with marine life

• Enhanced resistance to water pressure

• Increased visibility in murky waters

• Ability to create detailed images of the underwater environment

What is one limitation of using sonar technology in deep-sea exploration?

• Unlimited accuracy and range due to water density and composition.

• No interference from marine life.

• Accuracy and range limitations due to water density and composition.

• Enhanced visibility in deep-sea environments.

How does active sonar differ from passive sonar?

• Active sonar is more energy-efficient than passive sonar.

• Active sonar is used for underwater communication, while passive sonar is used for above-water communication.

• Active sonar emits light signals, while passive sonar emits sound signals.

• Active sonar emits signals, while passive sonar only listens.
