Question
The intensity of X-rays from collidge tube is plotted against wavelength λ as shown in the figure. The minimum wavelength found is λc and the wavelength of the Kα line is λk. As the accelerating voltage increased
Options
A.λk - λc increases
B.λk - λc decreases
C.λk increases
D.λk decreases
Solution
Wavelength λk is independent of the accelerating voltage (V), while the minimum wavelength λc is inversely proportional to V. Therefore, as V is increased, λk remains unchanged whereas λc decreases or λk - λc will increase.
