    1 / -0

    Statement - 1 : If the accelerating potential in an X - ray tube is increased, the wavelengths of the characteristic X - rays do not change.

    Statement - 2 : When an electron beam strikes the target in an X - ray tube, part of the kinetic energy is converted into X - ray energy.

    Solutions

    The wavelength of characteristic X - rays depends on the type of atoms 

    of which the target material is made. It does not depend on the 

    accelerating potential. Therefore, statement I is true. 

    When an electric beam strikes the target in an X - ray tube, part of the 

    kinetic energy is converted into X - ray energy. This statement is true. 

    But statement 2 does not explain statement 1.

    The correct answer is: Both Statement - 1 and Statement - 2 are true and Statement - 2 is not the correct explanation of Statement - 1.
