The `K_alpha` and `K_beta` X-rays of molybdenum have wavelengths `0*71 A` and` 0*63 A` respectively. Find the wavelength of `L_alpha` X-ray of molybdenum.

Explanation

To find the wavelength of the `L_alpha` X-ray of molybdenum, we can use the relationships between the energies of the electron shells and their corresponding wavelengths. Here’s a step-by-step solution:

### Step 1: Understand the relationships between the X-ray wavelengths
We know that:
- The wavelength of `K_alpha` X-ray (λ_Kα) is given as 0.71 Å.
- The wavelength of `K_beta` X-ray (λ_Kβ) is given as 0.63 Å.

The energy differences corresponding to these wavelengths can be expressed as:
