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?

The options

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.

The correct answer is option C)

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

Explanation:

Sound energy is referred to as the energy that is produced if an object is in vibration motion. The sound can be seen as the waves that move via a medium like water, solid and air. The solid medium is majorly metal or wood e.g. the guitar, piano e.t.c are forms of the sound energy-forming object.

The sound is regarded as a kind of mechanical energy. In this scenario, sound energy is produced by hitting the tuning fork with a mallet which is passed on as waves in the second tuning fork.

Therefore, the correct answer is option C.
