Assertion: If temperature is increased, fundamental frequency of an open pipe will increase. Reason: By increasing the temperature speed of sound wave will increase.

Options

  1. AIf both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
  2. BIf both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
  3. CIf Assertion is true but Reason is false.
  4. DIf Assertion is false but Reason is true.

Correct answer

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

Step-by-step solution

For an open pipe, (f=\frac{v}{2 \pi}). As temperature increases, speed of sound v increases, so the fundamental Trequency increases. Hence both Assetion and Reason are ture, and Reason correctly explains Assetion.
