The angle of incidence and the angle of reflection are

The normal drawn on the point P of a plane mirror helps to relate the angle of the incident ray and the angle of the reflected ray. According to the laws of reflection, The angle of incidence is equal to the angle of reflection and it is generally denoted as.

A perpendicular is drawn to point P, which divides both angles. A hard material such as concrete is as dissimilar as can be to the air through which the sound moves subsequently, most of the sound wave is reflected by the walls and little is absorbed. After detailed observations, scientists have concluded that the angle of incidence is equal to the angle of reflection. For this reason, acoustically minded builders of auditoriums and concert halls avoid the use of hard, smooth materials in the construction of their inside halls. When a wave reaches the boundary between one medium another medium, a portion of the wave undergoes reflection and a portion of the wave undergoes transmission across the boundary. convex mirror diverges rays and we can see only a virtual small image which appears to lie behind the mirror. It will only be present.Д¬oncave mirror converges light rays and forms real images on a screen. The virtual image can be formed on mirror but it will not remain there forever. The virtual image cannot be formed on scree whereas the real image can. real and virtual images are not the same. And the image that can be formed on a plain mirror is called virtual image.

The image which is formed on screen is called real image. This type of reflection is called diffuse reflection, and is what enables us to see non-shiny objects. It predicts that rays incident at slightly different points on the surface are reflected in completely different directions, because the normal to a rough surface varies in direction very strongly from point to point on the surface. For rough surfaces, the law of reflection remains valid. The law of reflection also holds for non-plane mirrors, provided that the normal at any point on the mirror is understood to be the outward pointing normal to the local tangent plane of the mirror at that point. The Laws of Reflection still apply but because the normals of the surface are all on different angles, light is scattered or diffused. Diffuse reflection occurs when light strikes a rough surface, as shown here. So, if incident rays are parallel, reflected rays are also parallel. Specular reflection is where light is reflected off a smooth surface. According to the law of reflection, the angle of incidence equals the angle of reflection. The angle of incidence is the angle between this normal line and the incident ray the angle of reflection is the angle between this normal line and the reflected ray. The convention used to express the direction of a light ray is to indicate the angle which the light ray makes with a normal line drawn to the surface of the mirror. Reflection involves a change in direction of the light ray. The Law of Reflection is when a ray of light strikes a plane mirror, the light ray reflects off the mirror.
