The wavelength of X-rays is in the range
The wavelength range of the visible spectrum extends from violet (400 nm) to red (750 nm). Express these wavelength in frequencies (Hz). (1 nm = 10−9 m).
There are found X-Rays with energy ranging from 2 KeV to 5 KeV. What is the minimum and maximum wavelength of X- Ray photon present respectively? (Take hc to be 1242 eV-nm)
