If $\mathrm{a}, \mathrm{b}, \mathrm{c}$ are the lengths of three edges of unit cell, $\mathrm{\alpha }$ is the angle between side $\mathrm{b}$ and $\mathrm{c}, \mathrm{\beta }$ is the angle between side $\mathrm{a}$ and $\mathrm{c}$ and $\mathrm{\gamma }$ is the angle between side $\mathrm{a}$ and $\mathrm{b},$ what is the Bravais Lattice dimensions of a tetragonal crystal?

Which among the following is the most symmetrical crystal system?

$\mathrm{Cu}$ crystallizes as face centred cubic lattice with edge length of $3.56\stackrel{°}{\mathrm{A}}$. What will be the nearest distance between $\mathrm{Cu}$ atoms?

A type of defect observed in stoichiometric compounds is Schottky defect. Schottky defect occur mainly in ionic compounds where

A common observation seen in ${\mathrm{Fe}}_3{\mathrm{O}}_4$ is that it is ferrimagnetic at room temperature but at $850 \mathrm{K}$ it becomes
