Physics Atomic and Nuclear Physics Atomic Structure MCQ (Single Correct)

Which one of the following statements is WRONG in the context of X-rays generated from a X-ray tube?

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

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

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

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

Text Solution

Verified by Experts

The correct answer is:

Cut off wavelength depends on the energy of the accelerated electrons and is independent of nature of target.

characteristic wavelength depend on atomic no and cut off wavelength depend on energy of
