Question

ASSERTION: The sound produced by the flute is more shrill than the sound produced by a table.
REASON: Frequency produced by the flute will be greater than the frequency produced by the table.
a)Both Assertion and reason are correct and reason is correct explanation for Assertion
b)Both reason and assertion are correct but Reason is not the correct explanation for assertion
c)Assertion is correct but the Reason is incorrect.
d)Assertion is incorrect but Reason is correct.

Answer 1

Hint: In the above question we are asked to basically verify the Assertion and the reason given to us. The frequency of the sound is directly proportional to the shrillness of the sound. Hence in the above question if the assertion is incorrect then we can say that the Reason is also incorrect and vice-versa. Hence accordingly we will verify the Assertion and the Reason.

Complete answer:
Our Assertion in the question says that the sound produced by the flute is more shrill than the sound produced by a table. This assertion is correct as for the same loudness the shrillness of the sound produced by the flute is greater than that of the table.
The shrillness of the sound is directly proportional to the frequency produced by an instrument. Hence our reason i.e. frequency produced by the flute will be greater than the frequency produced by the table, is also correct.
Therefore we can conclude that both the Assertion and the Reason given to us are correct.

So, the correct answer is “Option A”.

Additional Information:
It is also to be noted that the pitch is also directly proportional to the frequency of the sound. Therefore from this we can imply that the shrillness of the sound is directly proportional to the pitch of the where in both vary with frequency.

Note:
It is to be noted that it is not always necessary that the reason is the correct explanation of the Assertion. If there is a direct relation between the Assertion and the reason than only the reason holds valid for assertion. Hence we always need to confirm the assertion first and then the reason for the assertion.
