By colliding an electron beam with a heavy metal (i.e. heavy atoms) target, the wavelength of the EM radiation generated is in the Angstrom or nanoscale regime instead of micrometers as it is for visible light. The electron beam is accelerated in a vacuum tube and all its energy is converted into radiation, i.e. photons. Assume initial velocity  and energy of the electrons are negligible. What is the wavelength in Å of the accelerated electron just before it hits the target? Let m0 be the free electron mass of 9.11*10-31 kg, the electron charge q = 1.6*10-19 C; Planck’s constant h = 6.625 x 10-34 J-s;
