Q2) Consider a crystal of B-SiO2, a polymorph of the silicate, quartz, with lattice constants {a, a, c, 90, 90, 120}. What is the angle between the b axis and the direction [101]? What is the volume of the unit cell?

Step 1
To do this, we can use the dot product formula: cos(theta) = (b . [101]) / (|b| * |[101]|) where theta is the angle between the two vectors, b is the vector along the b axis, and [101] is the direction vector. We know that the lattice constants are {a, a, c, Show more…
