Question

For a given material the energy and wavelength of characteratic X-ray satisfy

• A. $E\left(K_{\alpha }\right)>E\left(K_{\beta }\right)>E\left(K_{\gamma }\right)$
• B. $E\left(M_{\alpha }\right)>E\left(L_{\alpha }\right)>E\left(K_{\alpha }\right)$
• C. $\lambda \left(K_{\alpha }\right)>\lambda \left(K_{\beta }\right)>\lambda \left(K_{\gamma }\right)$
• D. $\lambda \left(M_{\alpha }\right)>\lambda \left(L_{\alpha }\right)>\lambda \left(K_{\alpha }\right)$

Answer 1

Answer: (C), (D)

The correct options are
C $\lambda \left(M_{\alpha }\right)>\lambda \left(L_{\alpha }\right)>\lambda \left(K_{\alpha }\right)$
D $\lambda \left(K_{\alpha }\right)>\lambda \left(K_{\beta }\right)>\lambda \left(K_{\gamma }\right)$

M-series have the highest wave length and lowest energy.

Correct answer is $C,D$.
