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

(a)`0` to `oo`

B

(b)`lambda_("min")` to `oo` where `lambda_("min") gt 0`

C

(c)`0` to `lambda_("max")` where `lambda_("max") lt oo`

D

(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.

    How X - rays are produced ?

    Who invented X-rays?

    Statement-1 If the accelerating potential in an X-ray tube is increased, the wavelength of the characterstic X-rays do not change. because Statement-2 When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy.

    Write source and uses of X - rays.

    In an X-rays tube, electrons striking a target are brought to rest, causing X-rays to be emitted. In a paricular X-ray tube, the maximum frequency of the emitted continuum X-ray spectrum is f_(o) . If the votage across the tube is doubled, the maximum frequency is
