1.A powder diffraction pattern is recorded on a sample of an unknown elemental substance known to have cubic symmetry. Cu K-alpha x-rays (wavelength of 0.154 nm) are used and the 0 values of the first 7 peaks are 14.22, 23.64°, 28.05°, 34.550, 38.17°, 43.99° and 47.45° (a) What are the lengths of the reciprocal lattice vectors (or change in x-ray wave-vector) corresponding to these Bragg angles? (b) For a cubic structure, these lengths should be equal to (2r1/a)(h+k+P)2, although depending...

Each pattern shown below would appear on a screen when
monochromatic light first passes through a narrow slit of width a
and then strikes a screen. The darkest areas on the page represent
the brightest areas on the screen. In which case is the slit
illuminated with light of the longest wavelength? Why?

The diagram below shows the peaks of a traveling circular wave. The first peak that the source produced is shown in light green, the second in dark green, and the third is just about to be produced at the point in the center. Observer A stands to the right of the source, and observer R stands to the left. The grey lines are simply guidelines and do not represent anything physical. 1. This circular wave has a wavelength of λ....
