What is sound?

What is sound?

• A. A wave of energy
• B. A color
• C. A fixed tempo
• D. A musical instrument

Answer: (A)

Sound is a wave of energy that travels through a medium as vibrations created by something that moves. These vibrations cause pressure fluctuations in the surrounding air, water, or solids, forming mechanical waves that carry energy from the source to our ears. The other options describe different things: color is a property of visible light, a fixed tempo is a rhythmic speed used in music, and a musical instrument is an object that can produce sound rather than the sound itself. Sound has characteristics like pitch, determined by frequency, and loudness, determined by amplitude, and it requires a medium to travel.
