Question

Consider a metal used to produced some charateristic X - rays. Energy of X - rays are given by E and wavelength as represented by $\lambda$. Then which of the following is true:

• 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

The correct option is A $E\left(K_{\alpha }\right)>E\left(K_{\beta }\right)>E\left(K_{\gamma }\right)$
