Question

In x ray tube if filament voltage is increased by 50 and x ray tube voltage is increased by 100 then cut off wavenlength

Answer 1

Utilising the Duane–Hunt law you can determine the minimal wavelength of emitted x-rays, using the following formula:

λ=ℎ/

λ

m

i

n

=

h

c

/

e

V

Where h is Planck’s constant, c is speed of light and eV the applied potential (for this purpose, the same as KV).

So, in your case it would be:

λ=1.23984193/50=0.0247968386

λ

m

i

n

=

1.23984193

/

50

=

0.0247968386

p

m

But, as Cortland Richmond already wrote, the material of which the anode is a major part of what determines the wavelength of emitted x-rays.
