Question

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

• A. The colour of the object.
• B. The distance between the source of light and the object.
• C. The angle at which the light rays falls on the object.
• D. The size of the opaque object.

Answer 1

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

The correct options are
B The distance between the source of light and the object.
C The angle at which the light rays falls on the object.
D The size of the opaque object.

The size of the shadow depends on the distance between the source of light and the object, size of the opaque object and also on the angle at which the light rays falls on the object. It does not depend on the colour of the object.
