3. a) Draw a schematic diagram of an
X-ray diffractometer. [4 marks]
b) The results of an X-ray diffraction experiment that used
X-rays of wavelength 0.154 nm show the first 6 peaks at angles of
40.6°, 58.8°, 73.8°, 87.8°, 101.8°, and 116.4°.
i) Use this information to determine
the possible crystal structures of the sample. [10 marks]
ii) An additional scan was performed
on the sample and an additional peak was observed at an angle of
133.2°. Determine the crystal...

Draw PDA transition diagram for the following language:
The set of strings over the alphabet
{x, y} where 2 * (# of x's) = 3 *
(#y's)
That is, if we let nx be the number of x's and
ny be the number of y's, then the strings in these
language are those where 2nx = 3ny
Try to find a PDA that is as simple and elegant as possible
(do not convert from CFG).
