An x-ray tube is operated at 44300 V. Calculate the minimum wavelength of the radiation emitted by this tube.
If this radiation is directed at a crystal, the first-order maximum in the reflected radiation occurs when the angle of incidence is 2.17o. What is the spacing between reflecting planes in the crystal?
A laser with wavelength d/8 is shining light on a double slit with slit separation 0.3 {rm mm}. This results in an interference pattern on the screen a distance L away from the slits. We wish to shine a second laser, with a different wavelength, t..
