Regular reflection
Explanation:
Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions. This is called diffused reflection. Regular reflection or specular reflection leads to formation of images, as in the case of a cinema screen or plane mirror. Both surfaces are smooth and capable of specular reflection.
