Find mirror image of point representing x+i y on imaginary axis.(a) (x, y)(b) (-x, -y)(c) (-x, y)(d) (x, -y)This question was posed to me in an international level competition.I need to ask this question from Argand Plane and Polar Representation topic in section Complex Numbers and Quadratic Equations of Mathematics – Class 11

Answer» RIGHT choice is (C) (-x, y)

Explanation: MIRROR image of POINT (x, y) on IMAGINARY axis is (-x, y).

Since imaginary axis is acting as mirror y-coordinate remains same whereas x-coordinate gets inverted. So, (-x, y) is mirror image of (x, y) on imaginary axis.
