Assertion : The fundamental frequency of an open organ pipe increases as the temperature is increased. Reason : This is because as the temperature increases, the velocity of sound increases more rapidly than length of the pipe.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIfboth 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 both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.
