Embibe Experts Solutions for Exercise 4: Assigment

If the frequency of $K_{\alpha }X$-rays emitted from the element with atomic number $31$ is $v$ then the frequency of $K_a$ $\mathrm{X}$-rays emitted from the element with atomic number $51$ would be

$\mathrm{X}$-rays of a particular wavelength are used to irradiate sodium and copper surfaces in two separate experiments and stopping potentials are determined. The stopping potentials are

An $X$-ray tube has a short wavelength end at $0.45 \AA .$The voltage of tube is

The frequencies of $\mathrm{X}$-rays, $\gamma$-rays and U.V. rays are respectively $a, b$ and $c.$ Then

X-rays incident on a material

Penetrating power of $\mathrm{X}$-rays increases with increase in

If the potential difference $V$ applied to the coolidge tube is doubled, then the cut off wavelength

If the intensity of an X-ray becomes $\frac{I_0}{3}$ from I_ after travelling $3.5 \mathrm{cm}$ inside a target, then its intensity after travelling next $7 \mathrm{cm}$ will be
