Text Solution
Verified by Experts
The correct Answer is:
B
(b) Statement 1 : The wavelength of characteristic X- rays depends on the of atome of which the targetmate meterial is mode , it does not depend on the accelerating potential therefore statement 1 is true Statement 2 : when an electric beam strikes the target in an X- rays tube , part of the kinetic energy is converted into X- ray energy .This statement is true But statement 2 does not explain statement 1
