The type of rays that come together are called convergent rays.

Two intersecting rays.
Visible light rays are the only type of rays that are visible to the human eye. Other types of electromagnetic waves like infrared, ultraviolet, x-rays, and gamma rays are not visible.
infrared rays
Practice, practice, practice.

Technically, "cosmic rays" are high-energy particles rather than electromagnetic radiation. So no, they are not a type of light.
A)B-rays are the only type of radioactivity that is electrically charged. Alpha (a-rays) and gamma (y-rays) rays are both uncharged, or neutral, particles. B-rays, or beta particles, are high-energy electrons that are emitted from the nucleus of an atom and are the only type of radioactivity that is electrically charged.
