Question

What are the parameters to change size of the shadow?

• A. Distance between the object and the source of light.
• B. Distance between the object and the shadow.
• C. Different time intervals
• D. The size of shadow cannot be changed.

Answer 1

Answer: (A)

Distance between the object and the source of light.

Shadow size depends on the distance between the object and the source of light.
If we decrease the distance between the object and source of light, the size of the shadow increases and vice versa.
