JEE Main & Advanced Physics Ray Optics Question Bank Assertion and Reason

  • question_answer
    Assertion             :       The resolving power of an electron microscope is higher than that of an optical microscope. Reason                 :   The wavelength of electron is more than the wavelength of visible light.

    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: C

    Solution :

                The wavelength of wave associated with electrons (de Broglie waves) is less than that of visible light. We know that resolving power is inversely proportional to wavelength of wave used in microscope. Therefore the resolving power of an electron microscope is higher than that of an optical microscope.
