If `lambda_(min)` is minimum wavelength produced in X-ray tube and `lamda_(kalpha)` is the wavelength of `K_(alpha)` line. As the operating tube voltage is increased.

The minimum wavelength of X-rays produced in an X-ray tube at 1000 kV is

The intensity of X-rays form a Coolidge tube is plotted against wavelength lambda as shown in the figure. The minimum wavelength found is lambda_c and the wavelength of the K_(alpha) line is lambda_k . As the accelerating voltage is increased (a) lambda_k - lambda_c increases (b) lambda_k - lambda_c decreases (c ) lambda_k increases (d) lambda_k decreases

The intensity of X-rays from a coolidge tube is plotted against wavelength as shown in figure. The minimum wavelength found is lambda_c and the wavelength of the k_alpha line is lambda_k . As the accelerating voltage is increased.

The intensity of X - rays from a Coolidge tube is plotted against wavelength lambda as shown in figure -3.8 . The minimum wavelength as found is lambda_(C) and wavelength of the K_(alpha) - line is lambda_(K') . As the accelerating voltage is increased :

The intensity of X- ray from a coolidge tube is plotted againest wavelength lambda as shown in the figure . The minimum wavelength found lambda_(c) and the wavelength of the k_(a) line is lambda_(k) , As the accelerating voliage is increase

The intensity of X- ray from a coolidge tube is plotted againest wavelength lambda as shown in the figure . The minimum wavelength found lambda_(c) and the wavelength of the k_(a) line is lambda_(lambda) , As the accelerating voliage is increase
