^Intensity & penetration of X–rays

1. X–rays with high penetration power (wavelength range 1 A⁰ to 10 A⁰) are called hard. X-rays with low penetration power are called soft (wavelength range 10 A⁰ to 100 A⁰). Hard X-rays are produced at comparatively low pressure & high potential than soft X-rays.
2. The intensity & penetration of X-rays obtained by a Coolidge tube may be controlled independently.
3. The faster the incident electrons, the more penetrating the resulting X- Greater the number of electrons striking the target greater will be the intensity of the X-ray beam.
