Question

Which one of the following statements does not accurately describe vibrations? 

Answer 1

Which one of the following statements does not accurately describe vibrations?

A. Two bodies with the same vibration frequency that are placed next to each other will exhibit sympathetic vibrations as one body causes the other to vibrate.

B. Resonance occurs as a result of sympathetic vibrations.

C. Forced vibrations, such as those between a tuning fork and a large cabinet surface, result in a much lower sound than was produced by the original vibrating body.

D. A non-vibrating object can begin to vibrate as a result of forced vibrations.

THE ANSWER IS C I GOT IT 100% CORRECT ON MY EXAM.

Answer 2

The correct option is A.
When an end of a tuning fork that is vibrating is placed against a table, it produces a sounder that is dramatically louder than the original sound produced by the vibrating tuning fork. At this stage, the tuning fork is forcing the table to vibrate at its own frequency. Thus, the statement in option A is not true.
