Question

what do the unique properties of water allow sound to do differently than in air?
sound can be produces at higher frequencies in water than in air.
sound is easier to produce in water than in air.
sound travels further and faster in the water than in air.
sound cannot be heard in water.

Explanation:

To determine the correct answer, we analyze each option:

• "Sound can be produces at higher frequencies in water than in air" is incorrect. The frequency of sound production depends on the source, not the medium's unique properties related to propagation.
• "Sound is easier to produce in water than in air" is incorrect. Ease of sound production is about the source, not the medium's propagation - related properties.
• "Sound travels further and faster in the water than in air" is correct. Water is a denser medium than air, and sound (a mechanical wave) travels faster and can propagate further in denser media due to closer particle interactions.
• "Sound cannot be heard in water" is incorrect. Sound can be heard in water (e.g., marine animals use sound underwater), as water transmits sound waves.

Answer:

The correct option is: "Sound travels further and faster in the water than in air." (The checkbox corresponding to this statement should be selected.)
