142605 When two different material \(A\) and \(B\) having atomic number \(Z_1\) and \(Z_2\) are used as the target in coolidge \(\gamma\)-ray tube at different operating voltage \(V_1\) and \(V_2\) respectively their spectrums are found as below.

The correct relation is

142606 An \(X=\) ray tube operates on \(30 \mathrm{KV}\). What is the minimum wavelength emitted?
\(\left(h=6.6 \times 10^{-34} \mathrm{Js}, \mathrm{c}=3 \times 10^8 \mathrm{~ms}^{-1}, \mathrm{e}=1.6 \times 10^{-19} \mathrm{C}\right)\)

142607 The wavelength of the most energetic \(\mathrm{X}\)-ray emitted when a metal target is bombarded by \(100 \mathrm{keV}\) electrons is approximately.

142609 If the frequency of \(k_\alpha, X\)-ray of the element of atomic number 31 is \(f\), then the frequency of \(k_\alpha\), \(\mathrm{X}\)-ray for atomic number \(\mathbf{5 1}\) is

142611 Assertion: Soft and hard X-rays differ in frequency as well as velocity.
Reason: The penetrating power of hard \(\mathrm{X}\)-rays is more than the penetrating power of soft X-rays.
