Q. Electrons with energy $80\text{KeV}$ are incident on the tungsten target of an $\text{X}$-ray tube. $K$ shell electrons of tungsten have ionization energy $7.25\text{KeV}$. $\text{X}$-rays emitted by the tube contain only :

1. A continuous $\text{X}$-rays spectrum (Bremsstrahlung) with a minimum wavelength of nearly $0.155\dot{\text{A}}$
2. A continuous $\text{X}$-rays spectrum (Bremsstrahlung) with all wavelengths.
3. The characteristic $\text{X}$- rays spectrum of tungsten.
4. A continuous $\text{X}$- rays spectrum (Bremsstrahlung) with a minimum wavelength of $0.155\dot{\text{A}}$ and the characteristic $\text{X}$- rays spectrum of tungsten.

Q. For a given material, the energy $\left(E\right)$ and wavelength $\left(\lambda \right)$ of characteristic $\text{X}$-rays satisfies

1. $E\left(K_{\alpha }\right)>E\left(K_{\beta }\right)>E\left(K_{\gamma }\right)$
2. $E\left(M_{\alpha }\right)>E\left(L_{\alpha }\right)>E\left(K_{\alpha }\right)$
3. $\lambda \left(K_{\alpha }\right)>\lambda \left(K_{\beta }\right)>\lambda \left(K_{\gamma }\right)$
4. $\lambda \left(M_{\alpha }\right)>\lambda \left(L_{\alpha }\right)>\lambda \left(K_{\gamma }\right)$
