Energy of characteristic X-Ray is a consequence of
1 energy of projectile electron
2 thermal energy of target
3 transition in target atoms
4 none of these
Explanation:
C Characteristic X-rays is a unique property of individual elements and transition of an electron from outer shell to an inner shell gives a characteristics \(\mathrm{X}\) rays.

X-rays are a stream of
1 electrons
2 phonons
3 photons
4 protons
Explanation:
C X-rays are a stream of high-energy electromagnetic radiation which is knows as photon. \(\mathbf{X}\)-rays has a shorter wavelength and higher frequency than visible light, which allows them to penetrate through certain materials including human body.

According to the Moseley's law, the frequency of a spectral line in \(\mathrm{X}\)-ray spectrum varies as
1 atomic number of the element
2 square of atomic number of the element
3 square root of atomic number of element
4 fourth power of atomic number of the element
Explanation:
B According to Moseley's law, the frequency of a spectral line in X-rays spectrum varies as square of atomic number of the element. \(\mathrm{f}=(\mathrm{Z}-\phi)^2\)
