Question

Assertion (A): The sound produced by the humming bees can be easily heard by us.

Reason (R): The frequency of sound produced by humming bees is about 440 Hz, and it lies in the audible range, i.e, 20 Hz - 20,000 Hz.

Options

• If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

• If both Assertion and Reason are true, but Reason is not correct explanation of the Assertion.

• If Assertion is true, but the Reason is false.

• If Assertion is false, but the Reason is true.

Answer 1

If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.

Explanation:

Assertion (A) is true. The humming sound of bees can be heard by the human ear.

Reason (R) is true. The stated frequency, about \(440\ \text{Hz}\), lies within the human audible range of approximately \(20\ \text{Hz}\) to \(20{,}000\ \text{Hz}\).

Therefore, both A and R are true, and R correctly explains A.
