The light rays bounce off the table and all move in the same direction.
<h3><u>Explanation;</u></h3>
<em><u>When light hits a surface or a boundary it bounces of the surface a phenomenon called reflection, which is a property of waves.</u></em>
<em><u>Reflection of light depends on whether the surface is smooth or rough. </u></em><em><u>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.</u></em>
<em><u>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.</u></em>
