Interpretation:
If the X-ray with tungsten target is operating at a voltage of 50 kV, the short wavelength limit of the produced continuum needs to be calculated.
Concept introduction:
Short wavelength limit is calculated by using Planck’s constant using the following formula-
Here,
V= voltage

Answer to Problem 12.1QAP
Short wavelength limit of continuum is
Explanation of Solution
Short wavelength in X-ray tube is defined as the condition at which the intensity of spectrum is zero at a certain wavelength, where electrons transfer their energy into photon energy. This is given as-
On putting the values,
From equation (1)
Therefore,
Short wavelength of continuum is calculated by using Planck’s constant formula which is the ratio of constant value and the given voltage value. Therefore, calculated value of short wavelength is
