X-ray are produced in an X-ray tube operating at a given accelerating voltage. The wavelength of the continuous X-ray has values from.
(a) `0 to oo`
(b) `lambda_(min) to oo, where lambda_(min) gt 0`
(c ) 0 to `lambda_(max), where lambda_(max) ltoo`
(d) `lambda_(min) ot lambda_(max)`, where `0ltlambda(min) lt lambda_(max) lt oo`

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
