Question

c) Draw Ewald sphere in reciprocal lattice space (k-space) and show clearly by draw the
incident wave vector, Ko, scattered wave vector, K , vector G and direction of lattice
plane, that a reciprocal lattice point ( 3,-1) is one of the valid point for constructive
interference. Briefly explain why (3,-1) lattice is valid point. Is it the reciprocal lattice
point not on the surface of the sphere is valid point? Why?

Determine the probability that a photon is detected at the location of the first minimum of a 3-slit grating if the thrid slit is closed. You can assume that the magnitude of the probability amplitude due to each slit is r. (Hint: Start by showing how the complex amplitudes from each slit add up to zero at the first minimum. What is the resulting amplitude if the first amplitude is eliminated?)
