In vacuum,an electron of energy $10 \ keV$ hits a tungsten target. The emitted radiation will be:

If $\lambda_{Cu}$ is the wavelength of the $K_{\alpha}$ $X$-ray line of copper (atomic number $Z = 29$) and $\lambda_{Mo}$ is the wavelength of the $K_{\alpha}$ $X$-ray line of molybdenum (atomic number $Z = 42$),then the ratio $\frac{\lambda_{Cu}}{\lambda_{Mo}}$ is close to:

The intensity of the $X$-ray beam emitted in an $X$-ray tube is increased by........

For the production of characteristic $K_{\beta}$ $X$-rays,the electron transition is:

Calculate the wavelength of the $K_{\alpha}$ line for $Z=31$, when $a=5 \times 10^7 \, Hz^{1/2}$ for a characteristic $X$-ray spectrum.

The shortest wavelength of $X$-rays emitted from an $X$-ray tube depends on the
