If voltage across on X-ray tube is doubled, then energy of X-ray emitted by

A

be doubled

B

be quadrupled

C

become half

D

remain the same

Text Solution

Verified by Experts

The correct Answer is:
D
The energy of the X-ray depends on the nature of the target material.Thus the energy of the X-rays remain the same.

The stopping potential in a photoelectric experiment is linearly related to the inverse of the wavelength (1/lambda) of the light falling on the cathode. The potential difference applied across an X-ray tube is linearly related to the inverse of the cutoff wavelength (1/lambda) of the X-ray emitted. Show that the slopes of the lines in the two cases are equal and find its value.

Find the maximum potential difference which may be applied across an X-ray tube with tungsten target without emitting any characteristics K or L X-ray. The energy levels of the tungsten atom with an electron knocked out are as follows. Cell containing vacancy K L M Energy in keV 69.5 11.3 2.3
