Question: Two people stand 5 0 m apart and 3 0 m away
Two people stand 5.0 m apart and 3.0 m away from a large plane mirror in a dark room. At what angle of incidence should one of them shine a flashlight on the mirror so that the reflected beam directly strikes the other person?
Relevant QuestionsA beam of light is incident on a plane mirror at an angle of incidence of 35o. If the mirror rotates through a small angle of θ, through what angle will the reflected ray rotate? What is the cause of spherical aberration? Draw ray diagrams that show how three images of an object are formed in two plane mirrors at right angles, as shown in Fig. 23.27a. Figure 23.27b shows a similar situation from a different point of view that gives four ...An object is 120 cm in front of a convex mirror that has a focal length of 50 cm. (a) Use a ray diagram to determine whether the image is (1) real or virtual, (2) upright or inverted, and (3) magnified or reduced. (b) ...The upright image of an object 18 cm in front of a mirror is half the size of the object. (a) The mirror is (1) convex, (2) concave, (3) flat. Explain. (b) What is the focal length of the mirror?
