Chapter 28, Problem 28Q

To determine

Which line in X-ray spectrum corresponds to $K_{\alpha },K_{\beta },L$ etc. transitions

Answer to Problem 28Q

Solution:

X-rays produced by transition from $n=2ton=1$ levels correspond to $K_{\alpha }$

X-rays produced by transition from $n=3ton=1$ levels correspond to $K_{\beta }$

Explanation of Solution

We get X-ray emission when electron makes transition from higher energy levels to lower energy level. Each type of transition defines a specific X-ray.
