Worked Solution

Step 1: Non-luminous objects do not emit light. Step 2: For us to see them, light from a luminous source (like a lamp) must hit the object. Step 3: The light then reflects (bounces) off the object and enters our eyes.

Correct answer: Light from a source is reflected off the book into our eyes.
