Question

For production of characteristics $K_{\beta }$ X-ray, the electron transition will be :-

• A. n = 2 to n = 1
• B. n = 3 to n = 2
• C. n = 3 to n = 1
• D. n = 4 to n = 2

Answer 1

The correct option is C

n = 3 to n = 1

1. For production of characteristics $K_{\beta }$ X-ray, the electron transition will be n = 3 to n = 1.
2. n = 2 to n = 1, n = 3 to n = 2 and n = 4 to n = 2 are not the electron transitions for $K_{\beta }$ X-ray

Hence the option C is correct.
