A) Rectangle
B) Trapezium
C) Triangle
D) Square
Correct Answer: C
Solution :
[c] Draw an incident ray along the top side of rectangular strip, which happens to be parallel to the principal axis. After reflection this ray passes through focus. Hence image of all points (for e.g. \[{{O}_{1}},{{O}_{2}},{{O}_{3}}\] .......) on top side of the strip lie on this reflected ray (at \[{{I}_{1}},{{I}_{2}},{{I}_{3}}\].......) in between focus and centre of curvature. Thus the image of this strip is a triangle as shown in figureYou need to login to perform this action.
