The reflection of light can be roughly categorized into two types of reflection: specular reflection is defined as light reflected from a smooth surface at a definite angle, and diffuse reflection, which is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 1). The reflection of light can be roughly categorized into two types of reflection. All the smooth and shiny surfaces reflects light in a regular way forming images. It is due to the irregular reflection of light produced by the rough surface of a piece of white paper that we cannot see the image of our face on looking into the piece of paper. Reflection from a smooth, flat surface is called specular reflection. This means that light hitting the surface is scattered in a bunch of different directions.

For example : When a parallel beam of light falls on the smooth surface of a plane mirror, it is reflected as a parallel beam in only one direction.Images are formed by regular reflection of light. On rough surfaces, every ray of light has a different orientation after reflection. Specular reflection. Answer: (a) Reflection Explanation: When a ray of light falls on a smooth and polished surface, whole of light is returned back in the same medium. The law of reflection states that, for a smooth surface, when a ray of light is incident on the surface, the angle of incidence is equal to the angle of reflection. Reason: Since the angle of incidence and the angle of reflection are same, a beam of parallel rays of light falling on a smooth surface is reflected as a beam of parallel light rays in one direction only. This is called specular reflection. Which of the following results in diffused reflection? A common model for diffuse reflection is Lambertian reflectance, in which the light is reflected in accordance with Lambert's cosine law, see figure 2-3. Diffuse reflection is when light hits an object and reflects in lots of different directions. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called diffuse reflection. Regular reflection of light occurs from smooth surfaces like that of a plane mirror or highly polished metal surfaces. The size of image formed by the plane mirror is _____ as size of object. We usually notice reflections off a smooth surface. A rough surface reflects a parallel beam of light incident upon it in all directions. Irregular reflection or Diffused reflection: The phenomenon due to which a parallel beam of light, traveling through some medium, gets reflected in various possible directions, on striking some rough surface is called irregular reflection. Reflection by smooth surfaces is called. This type of reflection occurs on smooth surfaces such as a plane mirror. This is why if you are standing directly above a body of water, you can look down and see a reflection but also see the bottom of the pond or lake, at least in the shallow par.

Thus, the reflection of light can be roughly categorized into two types. Question 13. For diffuse reflection, the angle of incidence is greater than the angle of reflection. Irregular reflection of light. Question 12. Beam of light striking the reflecting surface is called A rough surface is said to have a "diffuse" reflection. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. Reflection from smooth surface is regular reflection. The reflection of light rays from a smooth surface is called specular reflection. This kind of reflection is called irregular or diffused reflection . Ungraded. Light reflects from a smooth surface at the same angle as it hits the surface. Answer: same. However, light strikes different parts of a rough surface at different angles, and it is reflected in many different directions ("diffused"). Examples of such reflection are those from mirrored surfaces and from still water surfaces (such as those of lakes,. Each Questions has four options followed by the right answer.
