The observatory upgraded their telescope to an alt-azimuth mount to improve tracking efficiency.

The gunner adjusted the azimuth circle before taking aim at the target.

The cartographers marked the azimuth circles on the map to indicate directional reference.

The captain instructed the crew to inspect the azimuth thrusters before entering the narrow channel.

The azimuthal quantum number determines the shape and angular characteristics of an atomic orbital.

In advanced spectroscopy lectures, azimuthal quantum numbers determine the shape of atomic orbitals and influence selection rules for electronic transitions.
