PART A

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 0.190 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.

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.
