In a certain x-ray tube, the electrons are accelerated by a pd of 12000V. Assuming all the energy goes to produce x-rays, determine the frequency of the x-rays produced. (Planks constant h = 6.62 ×10-34 J and charge of an electron, e = 1.6 ×10-19 C)
Energy of electrons = Qv = eV= 1.6×10-19×12000Energy of x-rays = hf = 6.62×10-34×ff = (1.6×10-19×12000)/(6.62×10-34 ) = 2.9×1018Hz
