Reflection In Plane Mirror Worksheet
Worksheet 3 pages and homework 1 page with answers for mirror diagrams including the law of reflection angles of incidence and reflection equal and the concept of virtual images.
Reflection in plane mirror worksheet. Two plane mirrors form the legs of a 60º angle. The light beam is reflected in a particular direction and can only be seen in that direction. As mentioned earlier the law of plane mirrors states that d i d o. They will then discover the characteristics of images formed in a plane mirror through a laboratory investigation.
Students will consider everyday examples of reflection to determine the law of reflection. The incident ray makes an angle with the normal to the surface called the angle of incidence θ i. Name for each of the following cases draw a ray diagram to show how the light rays reach the observer and to show the position of the virtual image in the mirror. The incident ray reflects at the mirror s surface according to the law of reflection.
Images in plane mirrors. Note that these angles are measured from the normal to either the incident or reflected rays. Includes measuring angles of incidence reflection. The angle of incidence equals the angle of reflection.
This is called specular reflection but with children we just call it mirror reflection figure 2a and 3a. If you are 3 m in front of the mirror your reflected image will be located 3 m behind the mirror. For plane mirrors the reflected image a virtual image and object are along the same line perpendicular to the reflective surface. Mirrors have a very smooth surface.
This reflection like all reflections obeys the law of reflection. When an object is placed between these two mirrors what is the maximum number of images that could be viewed while looking into the mirrors. In this lab you will study reflection of light from different mirrors. The reflected ray makes an angle with the normal to the surface called the angle of reflection θ r.
Since you drew the reflected ray in step 2 the point of incidence has already been determined. Thus the distance between you and the image. But rather than measuring angles you can merely draw the incident ray from the extreme of the object to the point of incidence on the mirror s surface. Figure 1 shows an example of reflection from a plane surface such as mirror.
Flashlight onto a mirror please try the set up of figure 31 then quite surprisingly one does not see a light spot on the mirror.
