Light reflectingfrom a smooth surface undergoes a change in its direction, but not in its speed.This phenomenon is referred to asspecular reflection.When a light ray comes into contact with a smooth surface, such as a mirror, it is reflected back at an angle that is equal to theangle of incidence.This is because the smoothsurfacereflects light uniformly, and the angle of incidence is always equal to the angle of reflection.There are two types of reflection: specular and diffuse.Specular reflectionis when light reflects from a smooth surface, such as a mirror or a pool of water, whilediffuse reflectionis when light reflects off a rough or irregular surface, such as a wall or a sheet of paper.This is because the light rays that come into contact with thesurfaceare scattered in many directions, making it difficult to see a clear image of thelight source.To know more aboutangle of incidence:brainly.com/question/27830617#SPJ11...
