Voltage applied between cathode and anode of an X-ray tube is 18 kV. Calculate the minimum wavelength of the X-rays produced.

Explanation

To solve the problem of calculating the minimum wavelength of the X-rays produced in an X-ray tube with a voltage of 18 kV, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula**:
The minimum wavelength (\( \lambda_{\text{min}} \)) of the X-rays produced can be calculated using the formula:
\[
\lambda_{\text{min}} = \frac{h \cdot c}{e \cdot V}
