X- rays are produced in an X- rays tube operating at a given accelerating voltage . The wavelength of the continuous X- rays has values from

Options

A. `0 and oo`
B. `lambda_(min) to oo , where lambda_(min) gt 0`.
C. `0 to lambda_(max), where lambda_(max) lt oo`.
D. `lambda_(min) to lambda_(max), where 0 lt lambda_(min) lt oo`.

Answer

A

Explanation

The continuous X-ray spectrum is shown in figure

All wavelength `gt lambda_(min)` are found where `lambda_(min) = (12375)/(V) Å`
Here, `V` is the applied voltage
