STATEMENT-1:If the accelerating potential in an X-ray tube is increased, the wavelengths of the characteristic -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 -ray energy.
STATEMENT-2:When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into -ray energy.
View answer and explanation
Correct option: B
Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1
Option B (Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1) is correct because characteristic X-ray wavelengths depend on the target material, not the accelerating potential, and the kinetic energy conversion is a separate fact.
