Question

An element of atomic number 16 has a wavelength i for the K line. What is the
wavelength of the K line emitted by an element of atomic number 31.​

Answer 1

Answer:

Let the wavelength of an element having atomic number 29 be λ′. Thus, the wavelength of Kα line for the element having atomic number 29 is four times that of the wavelength of an element having atomic number 57is4λ.
