Question

What are the factors that affect the size of a shadow?

• A. The colour of the object
• B. The distance between the object and the source of light
• C. The distance between the object and the screen
• D. The size of the opaque object

Answer 1

Answer: (B), (C), (D)

The correct options are
B The distance between the object and the source of light
C The distance between the object and the screen
D The size of the opaque object

The size of a shadow depends on the size of the object and its distance from the source of light and the screen. If the source of light is closer to the object, a larger shadow is formed. If the screen moves closer to the object, the shadow becomes smaller.
