A plane mirror is kept parallel to line $y = x$ as shown. An object is kept at ( $2, - 2, 0$ ). What is the y coordinate of the image formed ?

Answer:

Solution:

The mirror lies along a line parallel to $y = x$ ; reflection swaps the coordinates relative to that line.

Reflecting (2, -2) across $y = x$ gives (-2, 2).

The y-coordinate of the image is 2.

Answer: 2
