    Visulization of flux through differential area and solid angle. As always n ^ {\displaystyle \mathbf {\hat {n}} \,\!} is the unit normal to the incident surface A, d A = n ^ d A {\displaystyle \mathrm {d} \mathbf {A} =\mathbf {\hat {n}} \mathrm {d} A\,\!} , and e ^ ∠ {\displaystyle \mathbf {\hat {e}} _{\angle }\,\!} is a unit vector in the ...

  3. Ray (optics) - Wikipedia

    en.wikipedia.org/wiki/Ray_(optics)

    A meridional ray is a ray that passes through the axis of an optical fiber. A skew ray is a ray that travels in a non-planar zig-zag path and never crosses the axis of an optical fiber. A guided ray, bound ray, or trapped ray is a ray in a multi-mode optical fiber, which is confined by the core.

  4. Regiomontanus' angle maximization problem - Wikipedia

    en.wikipedia.org/wiki/Regiomontanus'_angle...

    In mathematics, the Regiomontanus's angle maximization problem, is a famous optimization problem [1] posed by the 15th-century German mathematician Johannes Müller [2] (also known as Regiomontanus). The problem is as follows: The two dots at eye level are possible locations of the viewer's eye. A painting hangs from a wall.

  5. Euclidean geometry - Wikipedia

    en.wikipedia.org/wiki/Euclidean_geometry

    Angles whose sum is a right angle are called complementary. Complementary angles are formed when a ray shares the same vertex and is pointed in a direction that is in between the two original rays that form the right angle. The number of rays in between the two original rays is infinite. Angles whose sum is a straight angle are supplementary ...

  6. Angle of incidence (optics) - Wikipedia

    en.wikipedia.org/wiki/Angle_of_incidence_(optics)

    The angle of incidence, in geometric optics, is the angle between a ray incident on a surface and the line perpendicular (at 90 degree angle) to the surface at the point of incidence, called the normal. The ray can be formed by any waves, such as optical, acoustic, microwave, and X-ray. In the figure below, the line representing a ray makes an ...

    The first equation is known as the eikonal equation, which determines the eikonal is a Hamilton–Jacobi equation, written for example in Cartesian coordinates becomes + + =. The remaining equations determine the functions A m ( r ) {\displaystyle A_{m}(\mathbf {r} )} .

  8. Intercept theorem - Wikipedia

    en.wikipedia.org/wiki/Intercept_theorem

    The intercept theorem, also known as Thales's theorem, basic proportionality theorem or side splitter theorem, is an important theorem in elementary geometry about the ratios of various line segments that are created if two rays with a common starting point are intercepted by a pair of parallels.

  9. Paraxial approximation - Wikipedia

    en.wikipedia.org/wiki/Paraxial_approximation

    In geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system (such as a lens). [1] [2] A paraxial ray is a ray that makes a small angle (θ) to the optical axis of the system, and lies close to the axis throughout the system. [1]
