A group of rays is called a "bundle of rays." In optics, this term is often used to describe a collection of light rays that are traveling in similar directions, which can be relevant in the study of lenses, mirrors, and other optical systems. In other contexts, such as physics or geometry, a group of rays originating from a common point may also be referred to as a "fan of rays" or simply a "ray cluster."

It largely depends on what type of fish. Generally, a group of fish is called a school. However, sharks are fish as well and a group of sharks is called a gam, herd, pod, or shiver. Rays are also fish, but groups of rays are called a fever, draught, drift, scale, school, or shoal. Eels, another type of fish, in a group are called a swarm. A group of barracuda are called a battery. A group of seahorses is a herd.
A Group Of Manta Rays is called a school. Just like a school of fish... Proof: Another wiki answer asking the same question, and a dictionary! .... :P
A group of sharks is called a gam, grind, school, herd, pod, collage, or shiver.
I've heard the term for a group of manta rays to be "A fever of manta rays"
The collective noun for rays is a "school." Rays are a type of cartilaginous fish that belong to the same family as sharks, known as elasmobranchs. When a group of rays swim together, they are referred to as a school, similar to how a group of fish is called a school.
A collection of rays is commonly referred to as a "pencil of rays." In geometrical optics, this term describes a group of rays that emanate from a single point or a common origin, often used to analyze light propagation and behavior in lenses and mirrors.
Light rays coming in are called incident light rays.
they are called UV, or Ultraviolet rays.
The light rays that bounce back are called reflected light rays.
A collection of rays is called a ray bundle.
