Question

Allen and his lab partner each held a tuning fork, frequency 440 Hz, in their hands. Allen tapped his tuning fork with a mallet and they listened to the sound it made. "Wait a minute!" exclaimed Allen's partner. "My tuning fork is vibrating too!" Sure enough, both tuning forks were vibrating although only Allen hit his with the mallet. How can you explain this? A) Sound waves are transferred to the tuning fork. B) Sound particles caused the second tuning fork to vibrate. C) Sound energy travelled as waves from one tuning fork to the other. D) Sound energy travelled as particles from one tuning fork to the other.

Answer 1

Answer:

The correct answer is option C. Sound energy traveled as waves from one tuning fork to the other.  

Explanation:

Sound energy is the energy that is generated if an object vibrates. The sound is basically is the waves that travel by a medium such as water, solid and air. the solid medium is usually metal or wood. guitar is one of the great examples of the sound energy-producing object.

The sound is one of the forms of mechanical energy. In this case, sound energy is generating by the hitting tuning fork with a mallet that is transferred as waves to the other tuning fork.

Thus, the correct answer is option C.

Answer 2

Answer:

C) Sound energy travelled as waves from one tuning fork to the other.

Explanation:

The air consists of particles. These particles transfer energy using waves.
