Rays of light transmitted in multimode fiber are called?

Explanation:
Rays of light in a multimode fiber are best described as modes. Each mode is a distinct electromagnetic field pattern that can propagate down the fiber while meeting the core–cladding boundary conditions. In multimode fiber there are many such patterns, corresponding to different angles and field distributions, so multiple rays travel simultaneously along different paths. This concept explains why signals in multimode fibers can spread over time (modal dispersion). Reflections and refractions describe boundary interactions, while waves is too general to capture the specific, guided propagation patterns inside the fiber.
