Each will reflect at an angle equal to its angle of incidence.
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 occurs such that the incidence angle is equal to the angle of reflection.
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.
