At the time of sunset, Lopa and Kritika are sitting facing each other. If the shadow of Lopa falls to the right of Kritika, in which direction is Kritika facing?
North
Understanding Directions and Shadows at Sunset
This question involves understanding relative directions and how shadows behave at a specific time of day, which is sunset. We are given a scenario with two people, Lopa and Kritika, sitting facing each other, and information about where Lopa's shadow falls relative to Kritika.
Shadow Direction During Sunset
The position of the sun determines the direction of the shadow. During sunset, the sun is in the West. Therefore, the shadow of any object or person will fall in the direction opposite to the sun, which is the East.
- Sun is in the West at sunset.
- Shadows fall towards the East at sunset.
Analyzing Lopa's Shadow
We are told that Lopa's shadow falls to the right of Kritika. We know that Lopa's shadow falls towards the East (because it's sunset). This means that Kritika's right side is towards the East.
- Lopa's shadow direction = East.
- Lopa's shadow falls to Kritika's right.
- Therefore, Kritika's right direction = East.
Determining Kritika's Facing Direction
Now we need to figure out which direction Kritika is facing if her right hand is pointing towards the East. Let's consider the standard directions:
- If you face North, your right is East, and your left is West.
- If you face South, your right is West, and your left is East.
- If you face East, your right is South, and your left is North.
- If you face West, your right is North, and your left is South.
Since Kritika's right is East, she must be facing North.
Verifying the "Facing Each Other" Condition
The question states that Lopa and Kritika are sitting facing each other. If Kritika is facing North, then Lopa must be facing South.
Let's check if Lopa's shadow falling East is consistent with her facing South:
- Lopa is facing South.
- The sun is in the West (sunset).
- Lopa's shadow will fall towards the East.
This is consistent. Lopa's shadow falls East, and if Kritika is facing North, East is indeed to her right.
Based on the analysis, Kritika is facing North.
| Time | Sunset |
|---|---|
| Sun Direction | West |
| Shadow Direction | East |
| Given | Lopa's shadow is to Kritika's right |
| Conclusion | Kritika's right is East |
| Kritika's Facing | North (since Right is East) |
Final Answer Determination
Following the steps and logical deductions, Kritika's facing direction is North.
Revision Table: Sunset Shadow Direction
| Time | Sun Position | Shadow Direction |
|---|---|---|
| Sunrise (Morning) | East | West |
| Noon (approx. 12 PM) | South (in Northern Hemisphere) | North (in Northern Hemisphere) |
| Sunset (Evening) | West | East |
Additional Information: Relative Direction Puzzles
Direction and shadow puzzles often require combining knowledge of the sun's position at different times of day with understanding relative directions (left, right, front, back). Key points to remember:
- Shadows are always opposite to the sun's position.
- Knowing which direction a person's left or right hand points tells you which way they are facing. For example, if your right is East, you must be facing North.
- If two people face each other, they face in opposite directions (e.g., North and South, East and West).
Practicing different scenarios with varying times of day (sunrise, noon, sunset) and different relative positions can help improve spatial reasoning skills needed for these types of questions.
