See Answer. A ray of light drawn from the sun's position at 7 pm to the distant window reflects off the window and travel to the observer's eye. On the other hand, a ray of light drawn from the 1 pm sun position to the window will reflect and travel to the ground, never making it to the distant observer's eye. 4.

Incident Ray:The ray of light that is incident on the interface.Reflected Ray:The ray of light that is reflected from the interface.Normal:The perpendicular to the interface.Angle of Incidence:The angle that the incident ray makes with the normal.In the case of specular reflection, the angle of reflection is equal to the angle of incidence, thus giving a mirror-like reflection.
In the case of diffuse reflection, the incident ray reflects from the interface in all directions. In other words, the angles of reflections are different for each reflected ray.
A mirror with a flat or planar reflective surface is called a plane mirror. The reflected angle is always equal to the incident angle for all the light rays, which strike the plane mirror. The angle that occupies within the incident ray & the normal is called the angle of incidence. The normal is said to be an imaginary line that is ...

Mar 23, 2022 · The law of reflection describes the type of reflection you see from a mirror. The angle between the incident ray and the normal is the same as the angle between the reflected ray and the normal. Another name for the normal is the perpendicular line, with respect to the surface. The incident ray, normal, and reflected ray all lie in the same plane.
The four steps of the process for drawing a ray diagram are listed, described and illustrated below. 1. Draw the image of the object. Use the principle that the object distance is equal to the image distance to determine the exact location of the object. Pick one extreme on the object and carefully measure the distance from this extreme point ...
Apr 15, 2015 · But in front of the mirror, the rays behave exactly as if they had come from behind the mirror, so that is where the image is situated. Figure 1. Two sets of rays from common points on an object are reflected by a flat mirror into the eye of an observer. The reflected rays seem to originate from behind the mirror, locating the virtual image.

The Law of Reflection Video Tutorial. The Law of Reflection Video Tutorial introduces the vocabulary of reflection (incident ray, reflected ray, angle of incidence, and angle of reflection) and describes and illustrates the law of reflection. The application of the law of reflection to the viewing of images in plane mirrors is explained.
