Determine whether an interference pattern is observed on the otherside of the slits in each experiment.a. An electro n beam is aimed at two closely spaced slits. The beamis attenuated (made dimmer) to produce only 1 electron perminute.b. An electron beam is aimed at two closely spaced slits. A lightbeam is placed at each slit to determine when an electron goesthrough the slit.c. A high-intensity light beam is aimed at two closely spaced slits.d. A gun is fired at a solid wall containing two closely spaced slits.(Will the bullets that pass through the slits form an interferencepattern on the other side of the solid wall?)

Question B1 The material rubidium antimony selenide, Rb3SbSe3, is known to have a cubic crystal structure. A diffraction experiment using Cu Ka radiation of wavelength X = 1.5406 Å showed peaks at 2012.319, 15.103°, 17.456°, 19.536°, 21.421°, and 24.784°. a) Index each of these peaks (that is, calculate possible h, k, and I values for each of them). Show that these data are consistent with a cubic unit cell, and calculate its unit cell parameter a. Which cubic Bravais lattice (i.e., simple cubic, body-centred cubic, or face-centred cubic) is most appropriate? On the other hand, the related compound rubidium manganese selenide, RbMnSe2, has a body-centred tetragonal structure with unit cell parameters a = 4.266 Å and c = 14.033 Å. Its motif consists of a Rb atom at (0, 0, 0), a Mn atom at (½, 0, 1), and Se atoms at (½, 1, 0.15) and (,,-0.15). b) Draw the unit cell of this structure in projection down the b axis, with the a axis vertical and the c axis horizontal.

2 X-Ray Diffraction d sin e to detector incident X-rays Diffraction patterns produced by X-rays can be used to determine the atomic structure of crystals. In a three-dimensional crystal, the diffraction peaks reveal the distance between planes of atoms. In this problem, we consider a one-dimensional crystal: a line of atoms. X-rays with a wavelength of å = 0.15nm are used in a diffraction experiment. The first diffraction peak occurs at an angle of 8.627°. (a) What is the separation between neighboring atoms? (b) At what angles will the next two peaks occur?

It has been suggested that solar powered space ships could get a boost from a laser either on Earth or in orbit around Earth. The laser would have to be very powerful to give any measurable benefit to the ship. If the laser produces a 0.1-m diameter beam of 446-nm light, what is the minimum angular spread of the beam? rad Additional Materials
