PSM V05 D043 Illustration of the reflection of light.jpg 1,419 × 993 440 KB. The law of reflection states that when a light ray reflects off a surface. In case of the plane mirrors the image formed or seen by the observer is seen in the direction in which the light is reflected in the same distance as the distance of the object from the mirror. Set targeted work quickly using your students data and save time marking. Figure 5.6: Ray diagram showing angle of incidence and angle of reflection. Note: The image formation process in plane mirrors and in spherical mirrors can be understood with the help of the laws of reflection of light. However, the angle incidence and the angle of reflection will remain the same even if the direction of the rays are changed. These two angles will always be equal.Ĭhanging the direction of the incident ray will result in the change in direction of the reflected ray, but they will always lie in the same plane. The angle of reflection is the angle which is made by the reflected ray with the normal to the surface. The angle of incidence is the angle which is made by the incident ray with the normal to the surface. Draw a ray diagram, labelling clearly the normal, incident ray, angle of incidence, reflected ray and angle of reflection accurately. As shown in the picture, the incident ray comes and strikes at the interface of the two mediums and reflects back to the first medium again, which is shown as the reflected ray.ġ.)The angle of incidence and the angle of reflection are equal to each other.Ģ.)The incident ray, the reflected ray and the normal to the surface at the point of contact of the incident ray, all lie in the same plane
