READING QUIZ 1 - Physics and Astronomy

What is the minimum accelerating voltage required to produce an x-ray with a wavelength of 0.0300 nm? (min = hc/eV using hc=1.989x10-25 J(m . Then V = hc/e(min = 4.14x104 V = 41.4 kV. Assuming that the tungsten filament of a lightbulb is a blackbody, what is its peak wavelength if its temperature is 2900 K? ................
