10 Scientists investigating the atomic structure of molecules often use a technique called X-Ray Diffraction. Time left In this technique, a beam of X-Rays is directed at a crystal of an unknown chemical molecule. The atoms in the crystal cause the X-Ray photons to diffract, as if the crystal was a diffraction grating with extremely tiny slit separation. In dent O o O ovo 9 o o o o o o In this context, the space between atoms in the molecule is the "slit separation'. In one such diffraction experiment, X-Ray Radiation = 0.10 nm) is incident on an unknown crystal. A detector located 10 cm away from the sample detects a pattern of nodes and antinodes, indicating that diffraction is occurring. The first antinode is detected 2.70 cm away from the central antinode. a) Based on the experimental details provided above, calculate the space between atoms in the crystal. (I mark) b) Scientists cannot use visible light to study inter-atomic spacing. Imagine the previous experiment was conducted using light with = 400 nm instead of the X-Rays. Calculate the distance between the central antinode and the first order antinode. Why is this distance unsuitable for typical laboratory studies? (2 marks) c) Instead of EMR, a beam of electrons can be used to investigate atomic spacing. What voltage would be required to accelerate electrons from rest to a sufficient velocity for their de Broglie wavelength to be 0.1 nm? (2 marks) SHOW ALL WORK done to find your answers.
