MCQ
Moseley's Law for characteristic $X-$ray is $\sqrt{\text{v}}=\text{a}(\text{z}-\text{b})$. Here,
  • ✓
    Both $a$ and $b$ are independent of the material.
  • B
    $a$ is independent but $b$ depends on the material.
  • C
    $b$ is independent but a depends on the material.
  • D
    Both $a$ and $b$ depend on the material.
✓

Answer

Correct option: A.
Both $a$ and $b$ are independent of the material.
Moseley's Law for characteristic $X-$ray is $\sqrt{\text{v}}=\text{a}(\text{z}-\text{b})$where, a and b are constants independent of the material used.
