The wavelength of the characteristic X-ray `K_(alpha)` line emitted from Zine `(Z = 30) is 1.415 Å`. Find the wavelength of the `K_(alpha)` line emitted from molybdenum `Z = 42)`.

Explanation

To find the wavelength of the Kα line emitted from molybdenum (Z = 42) using the given information about zinc (Z = 30), we can apply Moseley's law. Here’s a step-by-step solution:

### Step 1: Understand Moseley's Law
Moseley's law states that the frequency (ν) of the X-ray emitted is proportional to the square of the atomic number (Z) minus a constant (b). For Kα lines, we can express this as:
\[ \frac{1}{\lambda} \propto (Z - b)^2 \]
For Kα lines, \( b \) is typically taken as 1. Therefore, we can write:
