Question

Assertion

The sound produced by a flute is shriller than the sound produced by a tabla.

Reason

The frequency produced by a flute will be greater than the frequency produced by a tabla.

• A. Both assertion and reason are true and reason is the correct explanation of assertion.
• B. Both assertion and reason are true but reason is not the correct explanation of assertion.
• C. Assertion is true but reason is false.
• D. Assertion is false but reason is true.

Answer 1

The correct option is A

Both assertion and reason are true and reason is the correct explanation of assertion.

Explanation for assertion statement :

1. A sound of high frequency is called a shrill sound or high pitch sound.
2. The frequency of the sound produced by a flute is more than tabla.
3. Due to the high frequency of the sound produced in a flute as compared to a tabla, the sound produced by a flute is shriller than the sound produced by a tabla.
4. The graph below clearly shows that for a high pitch sound or shriller sound, frequency is more as is the case for the flute.
5. The graph below also shows that for a low pitch sound, frequency is low as is the case with tabla.

Explanation for reason statement :

1. The sound produced by a flute has more frequency due to the vibrations of the air column inside the flute.
2. Vibrations of the air column produce high-frequency sound in the flute.
3. In the case of a tabla, the vibrations produced in the membrane of the tabla produce a sound that has a low frequency.
4. More the frequency of the sound produced, the shriller the sound, and vice versa.

Thus, the assertion is correct and the reason is the correct explanation of the assertion.

Hence, option A is the correct answer.
