Measure the length of your shadow at 9 AM, 12 PM, and 4 PM with the help of your friend. Write down your observations: (i) At which of the given times is your shadow the shortest? (ii) Why do you think this happens?
(i)
Answer
The shadow is shortest at 12 PM (noon).
(ii)
Answer
At noon, the Sun is directly overhead, so sunlight falls almost vertically on the ground. This causes the shadow to fall directly beneath the object, making it shortest. At other times, the Sun is at an angle, creating longer shadows.
Explanation
(i) At noon, the Sun is at its highest position in the sky, directly overhead. (ii) The chapter explains that shadow size depends on the position of the light source relative to the object and screen.
