Frequency

/ˈfriːkwənsi/

noun … “how often a wave repeats in a unit of time.”

Electromagnetic Waves, Sound Waves, and signals in digital or analog electronics. Frequency determines key characteristics such as pitch in audio, color in light, and propagation behavior in radio and communication systems.

Clock Signals, determining the speed at which a CPU executes instructions or how data streams are synchronized.

Vector Field

/ˈvɛk.tər fiːld/

noun … “direction and magnitude at every point.”

Vector Field is a mathematical construct that assigns a vector—an entity with both magnitude and direction—to every point in a space. Vector fields are fundamental in physics, engineering, and applied mathematics for modeling phenomena where both the direction and strength of a quantity vary across a region. Examples include velocity fields in fluid dynamics, force fields in mechanics, and electromagnetic fields in physics.
