I think 'reflection' is the term you are looking for.
Reflection of light is the phenomenon where light rays bounce off a surface after striking it. A mirror and a smooth metal surface are two examples of objects that can reflect light.
The scientific term for bouncing light is "reflection." This occurs when light rays hitting a surface return in the opposite direction after striking the boundary of the surface.
This is the definition of the reflection of a light ray. The other term related to light rays is refraction, which is the bending of a light ray as it passes from one substance into another.
The scientific term for bounce off of is "reflect."
Reflection - the bouncing back of light rays from a surface, such as a mirror, without being absorbed.
when light 'bounces off' a surface, the technical term is that light is reflecting. if you're looking for the unscientific, descriptive word, it is scatter
The term that indicates the point where reflected light rays meet along an optical axis is the focal point.
The term that indicates the imaginary line extending straight out of the center of a reflective surface is called the "normal." This line is perpendicular to the surface at the point of incidence, where light rays strike the reflective surface. The normal is crucial for understanding the angles of incidence and reflection in optics.
The term for light bouncing off an object is "reflection." Reflection occurs when light rays strike a surface and rebound in various directions. This phenomenon is the basis for how we perceive the world around us through sight.
Refraction
Refraction is the term that describes the notion that light rays bend when they enter a new medium. This bending occurs due to a change in the speed of light as it transitions from one medium to another, causing the rays to change direction.
The term that describe bouncing back of a beam of light from an opaque surface is "reflection."
