Embibe Experts Solutions for Chapter: Atomic Physics, Exercise 1: Exercise 1

If the frequency of $K_{\mathrm{\alpha }} X-\mathrm{ray}$ emitted from the element with atomic number $31$ is $f$, then the frequency of $K_{\mathrm{\alpha }} X-\mathrm{ray}$ emitted from the element with atomic number $51$ would be (assume that screening constant for $K_{\mathrm{\alpha }}$ is $1$) :

X-ray beam can be deflected

Consider a photon of the continuous $X‐$ray coming from a coolidge tube. Its energy comes from

$50\%$ of the X-ray coming from a Coolidge tube is able to pass through a $0.1 \mathrm{mm}$ thick aluminium foil. If the potential difference between the target and the filament is increased, the fraction of the X-ray passing through the same foil will be

On operating an $X$-ray tube at $1 \mathrm{kV}$, $X$-rays of minimum wavelength $6.22 \mathrm{Å}$ are produced. If the tube is operated at $10 \mathrm{kV},$ then the minimum wavelength of $X$-rays produced will be

In an $X$-ray tube, electrons striking a target are brought to rest, causing $X$-rays to be emitted. In a particular $X$-ray tube, the maximum frequency of the emitted continuum $X$-ray spectrum is $f_0.$ If the voltage across the tube is doubled, the maximum frequency is

The production of characteristic X-rays is due to-

Characteristic $X-$Rays are not obtained in the spectrum of$\mathrm{H}-$atom because:-
