Question

Statement: If the stem of a tuning fork is placed on a table, the sound heard increases.
Reason: If the frequency of the forcing object and the natural frequency of the forced object are not equal, then objects are said to be in resonance. The frequency of the object undergoing resonance will increase.

• A. Both the Statement and Reason are correct.
• B. Both the Statement and Reason are incorrect.
• C. The Statement is correct but the Reason is incorrect.
• D. The Statement is wrong but the Reason is correct.

Hint:

Resonance occurs when frequencies match, not when they differ.

Answer 1

The Correct Option is C

Concept: Resonance and Sound Amplification
Step 1: Analyze the Statement}
When the stem of a tuning fork is placed on a table:

• The table acts as a sounding board.
• It increases the surface area vibrating.
• This amplifies the sound produced.

Hence, the Statement is correct. Step 2: Analyze the Reason}
The Reason states:

• Resonance occurs when frequencies are not equal → Incorrect
• It also says frequency increases during resonance → Incorrect

Correct concept: \[ \text{Resonance occurs when frequencies are equal} \] Step 3: Conclusion}

• Statement → Correct
• Reason → Incorrect

\[ \text{Correct answer: (C)} \]
