  1. Studying Coral Reefs

  2. Documenting Marine Life Behavior

  3. Monitoring Fish Populations

  4. All of the Above

Show answer
Correct Option: D
Explanation:

Underwater photography is used in marine biology for various purposes, including studying coral reefs, documenting marine life behavior, and monitoring fish populations.

What is the primary challenge faced by underwater photographers when capturing images in deep water?

  1. Low Light Conditions

  2. Strong Currents

  3. High Pressure

  4. All of the Above

Show answer
Correct Option: D
Explanation:

Underwater photographers face challenges such as low light conditions, strong currents, and high pressure when capturing images in deep water.

Which type of underwater camera housing is suitable for recreational diving?

  1. Professional Housing

  2. Compact Housing

  3. Sports Housing

  4. Deep-Sea Housing

Show answer
Correct Option: C
Explanation:

Sports housings are designed for recreational diving and provide protection for the camera while allowing easy access to controls.

What is the main purpose of using strobes in underwater photography?

  1. Adding Color to Images

  2. Increasing Depth of Field

  3. Reducing Backscatter

  4. All of the Above

Show answer
Correct Option: C
Explanation:

Strobes are used in underwater photography to reduce backscatter, which is the scattering of light by particles in the water.

Which of the following is a common type of underwater robot used for search and rescue operations?

  1. ROV (Remotely Operated Vehicle)

  2. AUV (Autonomous Underwater Vehicle)

  3. HOV (Human Occupied Vehicle)

  4. None of the Above

Show answer
Correct Option: A
Explanation:

ROVs are commonly used for search and rescue operations due to their ability to maneuver in confined spaces and their equipped with cameras and sensors.

What is the primary challenge faced by underwater robotics in exploring deep-sea environments?

  1. Extreme Pressure

  2. Lack of Light

  3. Strong Currents

  4. All of the Above

Show answer
Correct Option: D
Explanation:

Underwater robotics face challenges such as extreme pressure, lack of light, and strong currents when exploring deep-sea environments.

  1. Mapping Shipwrecks

  2. Searching for Artifacts

  3. Studying Underwater Ruins

  4. All of the Above

Show answer
Correct Option: D
Explanation:

Underwater robotics are used in marine archaeology for various purposes, including mapping shipwrecks, searching for artifacts, and studying underwater ruins.

What is the primary advantage of using HOVs (Human Occupied Vehicles) in underwater exploration?

  1. Increased Maneuverability

  2. Direct Observation

  3. Ability to Reach Greater Depths

  4. Reduced Operational Costs

Show answer
Correct Option: B
Explanation:

Which of the following is a common type of underwater robot used for mapping underwater terrain?

  1. ROV (Remotely Operated Vehicle)

  2. AUV (Autonomous Underwater Vehicle)

  3. HOV (Human Occupied Vehicle)

  4. None of the Above

Show answer
Correct Option: B
Explanation:

AUVs are commonly used for mapping underwater terrain due to their ability to cover large areas and collect data autonomously.

What is the primary challenge faced by underwater photographers when capturing images in shallow water?

  1. Low Light Conditions
