When you hear the term "ray" in the context of physics, it typically refers to a representation of the propagation of energy or information in a particular direction. The term "ray" does not imply whether it is a particle or a wave, as it can be used to describe both particle-like and wave-like phenomena, depending on the specific context.
In some cases, "ray" can refer to a particle-like behavior, such as in the concept of particle rays or ray tracing, where particles or streams of particles are considered to move along well-defined paths.
On the other hand, "ray" can also refer to a wave-like behavior, such as in the case of light rays or electromagnetic waves. In this context, a ray represents the direction of propagation of the wave. Light rays, for example, are often used to describe the paths along which light travels in straight lines.
So, whether a "ray" is considered as a particle or a wave depends on the particular phenomenon being described. It is important to consider the specific context and associated properties to determine whether the term "ray" refers to a particle-like behavior, a wave-like behavior, or a combination of both.
