A beam of electrons with kinetic energy 50 eV strikes the surface of a NaCI crystal. The spacing between the planes of the crystal is 0.281 nm. At what angle to the surface do we see a maximum in the reflected electron beam? (You can assume the electrons are nonrelativistic, and therefore K - p2/2m.) The same beam of electrons impinges on a pair of slits. A first-order diffration maximum is seen at 30 degrees to the incoming electron direction....

A coherent beam of 1.937 eV photons is incident on a double slit. A screen is L = 1.8 m away from the source and the width of each slit is a = .010 mm. This creates an interference/diffraction pattern such that the second interference maxima is y2 = 46 mm from the center line. If we wanted to duplicate this interference/diffraction pattern with monoenergetic electrons of mass me = 9*10-31 kg, what would the kinetic energy of one of...

1-A parallel beam of light from a laser with a wavelength 450 nm, falls on a grating whose slits are 1.28 x 10-4 cm apart. How far (in cm) is the 1st order bright spot from the center of the pattern on a screen 3.4 m away? 2-A grating whose slits are 3.2x10-4 cm apart produces a third-order fringe at a 25.0° angle. What is the wavelength of light that is used?
