Question

Choose the correct answer.
Sound can travel through

• A. gases only
• B. solids only
• C. liquids only
• D. solids, liquids and gases.

Answer 1

Answer: (D)

solids, liquids and gases.

Answer 2

Sound is a mechanical wave that requires a medium for propagation. It can travel through solids, liquids, and gases because it relies on the vibration of particles in the medium. In solids, particles are closely packed and transmit vibrations effectively. In liquids, particles are less dense but can still transmit sound waves. In gases, despite being less dense than solids and liquids, sound waves can travel through the compression and rarefaction of gas particles. Therefore, sound is capable of traveling through all three states of matter: solids, liquids, and gases.

So, the correct option is (D): solids, liquids and gases.
