Through what potential difference ΔV must electrons be accelerated (from rest) so that they will have the same wavelength as an x-ray of wavelength 0.150 nm ? Use 6.63×10−34 J⋅s for Planck's constant, 9.11×10−31 kg for the mass of an electron, and 1.60×10−19 C for the charge on an electron. Express your answer using three significant figures.
Answer is 66.9V
Part B
Through what potential difference ΔV must electrons be accelerated so they will have the same energy as the x-ray in Part A?
Use 6.63×10−34 J⋅s for Planck's constant, 3.00×108 m/s for the speed of light in a vacuum, and 1.60×10−19 C for the charge on an electron. Express your answer using three significant figures.
