Question

If the fluorescent radiation is strong then which of the following parameters to be used?

(a) Changing the path length of the secondary beam

(b) Changing the wavelength of the primary beam

(c) Keeping the wavelength of the secondary beam constant

(d) Changing the frequency of the secondary beam

This question was addressed to me in examination.

I want to ask this question from Sources of Background Radiation Fluorescence in division X-Ray Diffraction of Solid State Chemistry

Answer 1

Right answer is (b) Changing the wavelength of the primary beam

The best I can explain: When the fluorescent radiation is strong then the wavelength of the primary beam is changed generally by replacing an X-ray tube containing a copper target by one with an iron or molybdenum target.
