Question 3 • Physical Science

Which of these most directly affects what happens to white light when it hits an object?

Answer
A
the distance of the object from the light
B
the speed at which the light travels
C
the source of the light
D
the properties of the object

Explanation

The object’s properties—especially its material, surface, and pigments—determine which parts of white light it absorbs, reflects, or transmits. For example, an object looks red when it reflects red light and absorbs much of the other colors, so the correct choice is “the properties of the object.”
