Question

Closely observe the effect of light and shadow caused by the Sun on the spheres P, Q, R and S. Which is the correct option?

• A. P = 10 am, Q = 10:30 am, R = 12 noon, S = 6 pm
• B. P = 3 pm, Q = 6 am, R = 12 noon, S = 10:30 am
• C. P = 9:30 am, Q = 3 pm, R = 12 noon, S = 9 am
• D. P = 10:30 am, Q = 6 pm, R = 12 noon, S = 1 pm

Hint:

When analyzing shadows, consider the time of day and the position of the Sun relative to the object. Shadows will be longest in the early morning and late afternoon, and shortest around noon.

Answer 1

The Correct Option is D

Step 1: Understanding the effect of sunlight on objects.
The position of the Sun at different times of the day affects the direction and length of the shadow cast on the objects. In this case, the shadows cast by the spheres depend on the Sun's position relative to the objects.
Step 2: Analyzing the options.
(A) P = 10 am, Q = 10:30 am, R = 12 noon, S = 6 pm: This is incorrect based on the expected angles of light and shadow at these times.
(B) P = 3 pm, Q = 6 am, R = 12 noon, S = 10:30 am: This is incorrect, as it doesn't align with the typical sunlight positions and shadows.
(C) P = 9:30 am, Q = 3 pm, R = 12 noon, S = 9 am: This is incorrect, as the shadows do not match the expected results for these times.
(D) P = 10:30 am, Q = 6 pm, R = 12 noon, S = 1 pm: This is correct, as it accurately represents the time of day when the shadows are cast according to the Sun’s position.
Step 3: Conclusion.
The correct answer is (D) because it matches the expected positions of the Sun and the resulting shadows on the spheres.
