If the `K_alpha` radiation of `Mo (Z = 42)` has a wevelength of `0.71Å`, calculate wevelength of the corresponding radiation of `Cu,i.e. , k_(alpha)for Cu (Z = 29)` assuming b = 1.

Explanation

To solve the problem, we need to find the wavelength of the K_alpha radiation for Copper (Cu, Z = 29) given the wavelength of K_alpha radiation for Molybdenum (Mo, Z = 42) and using the formula that relates the wavelengths with atomic numbers.

### Step-by-Step Solution:

1. **Identify Given Values:**
- Wavelength of K_alpha radiation for Mo (Z = 42):
\[
\lambda_1 = 0.71 \, \text{Å}
