![]() When light travels from a medium with a low refractive index to a medium with a higher refractive index, it slows down and refracts closer to the normal line. Refraction is the bending of light due to the change in its speed when it obliquely passes two different media.Irregular reflection or diffuse reflection occurs when light strikes a rough surface, and light rays are reflected in random directions.Regular reflection, also known as specular reflection occurs when light strikes a smooth surface like a mirror, and light rays are reflected in one direction.There are two types of reflection: regular reflection and irregular reflection. This law states that the angle of incidence, the angle of reflection, and the normal line are found on the same plane and the angle of incidence is equal to the angle of reflection. ![]() The relationship between the angle of incidence and the angle of reflection is illustrated in the law of reflection. These angles are called angle of incidence and angle of reflection, respectively. The incident ray and the reflected ray form angles with the normal line, which is a line perpendicular to the reflecting surface. After hitting the surface, it bounces off as a reflected ray. The ray of light that hits the reflecting surface is called an incident ray. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection. Common examples include the reflection of light, sound and waterwaves. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. This phenomenon can be described using light rays. Reflection occurs when light bounces back as it hits a reflecting surface, such as a mirror.
