Question

what are \illuminated\ objects?
objects that produce and give off light
objects that reflect or absorb light

Explanation:

Illuminated objects do not produce their own light. Instead, they reflect or absorb light from other sources. For example, the moon (shown in the image) is an illuminated object as it reflects sunlight. Objects that produce and give off light are called luminous objects (e.g., the sun, a light - bulb).

Answer:

objects that REFLECT or ABSORB light
