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

Solution
The correct option is B Statement-1 is True, Statement-2 is True; Statement -2 is NOT a correct explanation for Statement-1.
The wavelength of characteristic x-ray depend on the atomic number of the target element and is independent of accelerating voltage in the x-ray tube. When an electron beam strikes the x-ray tube, a part of kinetic energy is converted into x-ray energy. Both statements are true, but statement 2 is NOT an explanation for statement 1.
