16. Assertion (A): Keeping a point object fixed, if a plane mirror is moved, the image will also move. Reason (R): In the case of a plane mirror, distance of object and Its image is equal from any point on the mirror. a) Both A and R are true and R is the correct explanation of A. b) Both A and R are true but R is not the correct explanation of A. 17. c) A is true but R is false. d) A is false but R is true. Assertion (A): A ray of the light incident along the normal to the plane mirror retraces its path after reflection from the mirror. 18. 19. 20. Reason (R): A ray of light along the normal has an angle of incidence as 7 and hence, it retraces its own path after reflection from the mirror. a) Both A and R are true and R is the correct explanation of A. b) Both A and R are true but R is not the correct explanation of A. c) A is true but R is false. d) A is false but R is true. Assertion (A): If both the object and plane mirror are moved through a distance of x then the image moves through a distance of 2x. Reason (R): If the object is fixed and plane mirror is moved through a distance x then the image also moves through a distance of 2x. a) Both A and R are true and R is the correct explanation of the assertion. b) Both A and R are true but R is not the correct explanation of A. c) A is true but R is false. d) A is false but R is true. Assertion (A): An object is placed at a distance of f from a convex mirror of focal length f, its image will form at infinity. Reason (R): The distance of an image in a convex mirror can never be infinity. a) Both A and R are true and R is the correct explanation of A. b) Both A and R are true but R is not the correct explanation of A. d) A is false but R is true. c) A is true but R is false. Assertion (A): Linear magnification of a mirror has no unit. Reason (R): The ratio of height of the image to the height of the object is the linear magnification produced by mirror. a) Both A and R are true and R is the correct explanation of A. Activa b) Both A and R are true but R is not the Go to Se correct explanation of A.
