This page covers Agniveer Air Force Mirror & Water Images with complete concept notes, 44 graded practice MCQs, key points and exam-specific tips. Free to study.
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
→Water Image
When an object is reflected in water below it, you get its water image. The image appears flipped vertically
💡KEY RULES
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

Exam Patterns
What examiners ask — read before attempting PYQs
📋SSC CGL typically asks
1
Write letters in reverse order: M-A-X-E
2
Reverse each letter individually:
- E becomes reversed E
- X remains X (symmetrical)
- A becomes reversed A
- M becomes reversed M
3
Final answer: Reversed M, Reversed A, X, Reversed E
WORKED EXAMPLE 2:
Question: Find water image of triangle with base at bottom
1
Identify the orientation (base at bottom)
2
Flip vertically - base moves to top
3
All other features flip accordingly
4
Answer: Triangle with base at top
SHORTCUT TRICK #2 - SYMMETRICAL LETTERS:
Symmetrical letters need no change:
- Horizontally symmetrical: A, H, I, M, O, T, U, V, W, X, Y
- Vertically symmetrical: B, C, D, H, I, O
- Use this to eliminate wrong options quickly
SHORTCUT TRICK #3 - DIRECTION ARROWS:
For arrows in mirror/water images:
- Mirror: Left arrow becomes right arrow
- Water: Up arrow becomes down arrow
- Combined: Diagonal arrows flip completely
COMMON MISTAKE #1:
Students confuse mirror and water images
💡Remember
- Mirror = Side mirror of car (horizontal flip)
- Water = Lake reflection (vertical flip)
Many students apply wrong transformation and lose easy marks
💡ADVANCED TIP
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
