    Study Notes

    Rays and Beams

    Definitions

    • Ray: A line that extends infinitely in both directions, defined by two points.
    • Beam: A set of rays that originate from a single point or line.

    Characteristics

    • Rays:
      • Extend infinitely in both directions
      • Have no thickness or width
      • Can be represented by a single point and direction
    • Beams:
      • Composed of multiple rays
      • Can be used to model light, sound, or other forms of radiation
      • Can be characterized by their direction, intensity, and divergence

    Types of Beams

    • Pencil Beam: A beam with a very small divergence, often used to model laser beams
    • Collimated Beam: A beam with parallel rays, often used to model light from a distant source
    • Diverging Beam: A beam with rays that spread out from a single point, often used to model light from a point source

    Applications

    • Optics: Beams are used to model light behavior in optical systems, such as lenses and mirrors
    • Acoustics: Beams are used to model sound waves in acoustic systems, such as loudspeakers and microphones
    • Radiation Therapy: Beams are used to model radiation treatment in cancer therapy
