Question 1

Potassium Iodide (chemical formula: KI) has a face-centered cubic structure (just like sodium chloride). If the distance between crystal planes is d = 0.353 nm and X-rays of wavelength λ = 0.0934 nm are used, what is the smallest angle θ at which a diffraction maximum may be obtained?

Question 2

Scattered light in the atmosphere is often partially polarized. The best way to determine whether or not light from a particular direction in the sky shows polarization is to

◦

diffract the light through a single slit.

◦

squint while looking in that direction.

◦

rotate a piece of polaroid film about an axis parallel to the ray while looking through it in that sky direction.

◦

rotate a piece of polaroid film about an axis perpendicular to the ray while looking through it in that sky direction.

◦

reflect the rays from that direction on a shiny metal surface.
