The wavelength of continuous X-rays is independent of the atomic number of the target material. The wavelength of characteristic X-rays depends on the atomic number of the target material.

Solution

Q.
Which one of the following statements is WRONG in the context of X-rays generated from a X-ray tube [2008]

1 Wavelength of characteristic X-rays decreases when the atomic number of the target increases

2 Cut-off wavelength of the continuous X-rays depends on the atomic number of the target

3 Intensity of the characteristic X-rays depends on the electrical power given to the X-ray tube

4 Cut-off wavelength of the continuous X-rays depends on the energy of the electrons in the X-ray tube

Ans.
(2)

The wavelength of continuous X-rays is independent of the atomic number of the target material. The wavelength of characteristic X-rays depends on the atomic number of the target material.
