The astronomer adjusts the azimuthal mount of the telescope.

Definition

1. Adjective:
   • Relating to azimuth: Pertaining to or measured by an azimuth, which is the horizontal angular distance from a reference direction (usually true north) to a point or line.

Usage

• The term "azimuthal" is primarily used in technical fields such as astronomy, navigation, cartography, and physics to describe angles, measurements, projections, or symmetry related to the azimuth.
• It is often used attributively before a noun (e.g., azimuthal angle, azimuthal projection).

Examples

• Adjective:
  • The telescope's mount allows for precise azimuthal adjustment.
  • An azimuthal equidistant projection map is centered on the North Pole.
  • The antenna has an azimuthal rotation of 360 degrees.

Advanced Usage

• "azimuthal symmetry": A property where a system's physical characteristics do not change when rotated around a central axis.
  • The electric field of a point charge exhibits azimuthal symmetry.
• "azimuthal quantum number": In atomic physics, a quantum number (denoted by ) that determines the shape of an electron's orbital and its orbital angular momentum.

Variants and Related Words

• Azimuth (n): The horizontal angle or direction.
• Azimuthally (adv): In an azimuthal manner or direction.

Synonyms

• Directional: Pertaining to direction.
• Horizontal-angle (as a compound descriptor): Related to the horizontal angle measurement.

Related Phrases and Technical Terms

• Azimuthal projection: A map projection where the surface of a sphere is projected onto a plane, preserving directions from a central point.
• Azimuthal angle: The angular coordinate in a spherical coordinate system that measures rotation around the vertical axis.
