Answer. According to the law of reflection, the angle of incidence equals the angle of reflection. Specular reflection is where light is reflected off a smooth surface. The Laws of Reflection still apply but because the normals of the surface are all on different angles, light is scattered or diffused.
Which type of reflection obeys the law of reflection?
one thing that you must know that ‘laws of reflection are defined for A POINT, NOT FOR A SURFACE’. These are valid for a plane mirror as well as for a spherical mirror. on rough surfaces also, A light ray ,microscopically, falls over a point thus every point reflect it, obeying the laws.
What is the main condition for diffuse reflection?
Diffused reflection is observed when the surface isn’t smooth. This means that at different points on the surface, the normal is different. The angle of reflection is STILL equal to the angle of incidence at THAT POINT and the NORMAL is unique at THAT point in the surface.
What do you mean by diffuse reflection?
Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles, rather than at just one angle as in the case of specular reflection.
What is the main difference between diffuse and scattered reflection?
Reflection occurs in one particular direction , from a smooth surface, the angle of reflection being equal to the angle of incidence. Scattering is diffuse reflection , from a rough surface, in all possible directions.
What is the difference between specular and diffuse reflection?
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).
What is Laws of reflection?
The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
What is a normal ray?
When a line is drawn perpendicular to the reflecting surface at the point of incidence, this line is known as normal. It is the imaginary line which is perpendicular to the reflecting surface. The normal ray is incident at 90 degrees to the reflecting surface.
What is meant by normal in reflection?
Answer: A ray of light which falls on a mirror is called the incident ray. A ray of light which is sent or reflected back by the miror is called reflected ray. Normal is a line drawn perpendicular to the surface of mirror from point the point where incident ray meets the surface of the mirror.
