The light rays bounce off the table and all move in the same direction.
Explanation;
When light hits a surface or a boundary it bounces of the surface a phenomenon called reflection, which is a property of waves.
Reflection of light depends on whether the surface is smooth or rough. When the light hits a smooth surface it bounces off the surface and all the rays of light moves in the same direction, this type of reflection is called specular reflection.
On the other hand , when right rays hits a rough surface the rays bounces off the surface and the rays move in different directions, a type of reflection called diffuse reflection.
