JEE Main & Advanced Physics Wave Mechanics Question Bank Assertion and Reason

  • question_answer
    Assertion             :       Sound travel faster in solids than gases. Reason                 :       Solid possess greater density than gases.  [AIIMS 2000]

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

    B)             If both assertion and reason are true but reason is not the correct explanation of the assertion.

    C)             If assertion is true but reason is false.

    D)             If the assertion and reason both are false.

    E)             If assertion is false but reason is true.

    Correct Answer: B

    Solution :

                       Since, velocity of sound, \[v=\sqrt{\frac{E}{\rho }}\] As, the elasticity of solid is large than that of gases. Hence, it is obvious that velocity of sound is greater in solids than in gases.
