Worked Solution

Step 1: Flat surfaces reflect light in a predictable, uniform way (specular reflection). Step [2-9]: Crumpled surfaces have uneven faces that scatter light in multiple directions (diffuse reflection). Step [2-9]: Scattered light does not form a clear image.

Correct answer: Light is reflected in many different directions by the crumpled foil.
