A wire is bent in the shape of a right angled triangle and is placed in front of a concave mirror of focal length f, as shown in the figure. Which of the figures shown in the four options qualitatively represent(*) the shape of the image of the bent wire ? (These figures are not to scale.)?
Answer (D)
solution
Distance of point A is f/2 Let A' is the image of A from mirror, for this image
image of line AB should be perpendicular to the principle axis & image of F will form at infinity, therefor correct image diagram is
