X- rays are produced in an X- rays tube ...

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

A

`0` to `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 lambda_("min") lt oo`

Text Solution

Verified by Experts

The correct Answer is:
B
The continuous X-ray specturm is shown in figure.

All wavelength `gt lambda_("min")` are found,
where `lambda_("min")=12375/("V(in volt)") Å`
Hence, V is the applied voltage.
