When a vibrating tuning fork is placed on a table, a loud sound is heard. This is due to : A. Reflection B. Refraction C. Forced vibrations D. Damped vibrations

The correct answer is: C. Forced vibrations

When a vibrating tuning fork is placed on a table, the table vibrates at the same frequency as the tuning fork. This is because the table is forced to vibrate by the tuning fork. The forced vibrations of the table cause the air molecules around the table to vibrate, which produces sound waves. The sound waves travel through the air and reach our ears, where they are converted into electrical signals that are

Reflection, refraction, and damped vibrations are not the correct answers because they do not explain why a loud sound is heard when a vibrating tuning fork is placed on a table.

Reflection is the bouncing of a wave off of a surface. Refraction is the bending of a wave as it passes from one medium to another. Damped vibrations are vibrations that gradually decrease in amplitude over time.

In the case of a vibrating tuning fork placed on a table, the sound is not caused by reflection, refraction, or damped vibrations. The sound is caused by forced vibrations.
