The wavelength of X-ray photon depends upon kilo voltage.
The wavelength of X-rays is inversely proportional to their energy, and the
energy of X-ray photons is determined by the kilo voltage (kV) used in the X-ray
tube. Higher kV results in higher energy and shorter wavelength photons, which
are more penetrating and are used for imaging denser tissues, while lower kV
results in lower energy and longer wavelength photons, which are less
penetrating and are used for imaging softer tissues. The other factors mentioned
(milli amperage, distance between source and object, and quantity of electrons
in the cathodic stream) affect the intensity of the X-ray beam but not the
wavelength of the photons.
