RRB Group D Mirror & Water Images

Mirror Image: When you place a vertical mirror on the right side of an object, you get its mirror image. The image appears reversed horizontally

When an object is reflected in water below it, you get its water image. The image appears flipped vertically

Mirror Image Rules: - Left becomes right, right becomes left - Top and bottom positions remain same - Curves change direction (C becomes reversed C) - Numbers: 3 becomes reversed 3, 7 becomes reversed 7 Water Image Rules: - Top becomes bottom, bottom becomes top - Left and right positions remain same - Curves flip vertically (smile becomes frown) - Letters like M become W, p becomes d FORMULA BLOCKS: Mirror Image: Horizontal flip (left-right reversal) Water Image: Vertical flip (top-bottom reversal) Combined: Both horizontal and vertical flip

- Mirror = Side mirror of car (horizontal flip) - Water = Lake reflection (vertical flip) Many students apply wrong transformation and lose easy marks

For complex shapes, focus on one distinctive feature (like a small circle or line). Track how this feature moves in the transformation. This saves time and reduces confusion
