The voltage applied to an X-ray tube is 20 kV. The minimum wavelength of X-ray produced, is given by `(31xxn)/50 Å` then n will be (`h=6.62xx10^(-34) Jx,c=3xx10^(8) m//s, e=1.6xx10^(-19)` coulomb):

Explanation

To find the value of \( n \) in the equation for the minimum wavelength of X-ray produced, we can follow these steps:

### Step 1: Understand the relationship between voltage and wavelength
The minimum wavelength (\( \lambda_{min} \)) of X-rays produced in an X-ray tube can be calculated using the formula:
\[ \lambda_{min} = \frac{hc}{eV} \]
where:
