There is no scientific term for what happens when light hits an opaque object I'm afraid to say.
When light cannot pass through an object, it is called opacity. This means that the material does not allow light to travel through it and blocks the transmission of light.
When a beam of light falls on a surface, it is called reflection if it bounces off the surface, or refraction if it passes through the surface and changes direction.
This is called opacity. Materials that are opaque do not allow light to pass through them.
A star in which light cannot escape because of its immense gravitational pull at its surface is called a black hole.
Reflection.
No, a ray cannot refract on an opaque surface because refraction occurs as light passes through a transparent or translucent medium, causing it to change direction. Opaque surfaces do not allow light to pass through, so refraction cannot occur on them.
An optically opaque material.
Materials through which light cannot pass are called opaque materials. Examples include wood, metals, and thick plastics.
The place where light cannot reach because an object is blocking it is called a "shadow." In the context of an opaque object, such as a planet or a solid object, it prevents light from passing through, creating an area of darkness behind it. Shadows vary in size and intensity depending on the light source and the distance between the object and the surface where the shadow is cast.
One example of an object that allows light to pass through but cannot be seen through is frosted glass. Frosted glass has a textured surface that scatters light as it passes through, making it difficult to see objects on the other side clearly.
When light changes direction as it passes through a boundary.
