These are some tips to remember the following easily
wavelength of X-rays produced and the dependence of wavelength and energy on the accelerating potential etc.
The energy of a photon of wavelength λ is given by E = 12345/λ, where E is in
electron volt and wavelength λ is in à... units.
If V is the accelerating potential applied to an X-ray tube, the wavelength of
continuous X-rays produced is given by, λ = 12345/V , where λ in angstrom ...
