X-ray diffraction is used to study the structure of crystallized proteins, nucleic acids, and other biological macromolecules. It was actually the technique used to study the structure of DNA in the early 1950s. X-rays of wavelength 0.24 nm are to used to study the structure of a protein. One of the maxima in intensity is located at 0.8 rad from the crystal planes responsible for this maximum.
1. Which wavelength of x-ray listed below would give you a maximum at the same location?
a. 0.55 nm
b. 0.33 nm
c. 0.77 nm
d. 0.44 nm
2. If this is the first maximum for the X-rays of wavelength 0.22 nm, what is the crystal plane separation of the protein that is responsible?
a. 0.16 nm
b. 0.31 nm
c. 0.14 nm
d. 0.22 nm
