Question

What are the two features of X-ray emission spectrum of an element such as copper?

(a) Monochromatic peaks and wavelength

(b) X-ray radiation and frequency

(c) Electric field and wavelength

(d) Magnetic field and monochromatic peaks

The question was posed to me in quiz.

My question is based upon X-rays and their Generations topic in portion X-Ray Diffraction of Solid State Chemistry

Answer 1

Correct choice is (a) Monochromatic peaks and wavelength

Best explanation: The X-ray emission spectrum of an element such as copper has two features. The intense, monochromatic peaks, caused by electronic transitions within the atoms, have wavelengths that are characteristic of the element i.e. copper. These monochromatic peaks are superposed on a background of ‘white radiation’.
