Why can a contact shadow be darker than a cast shadow?
Answer and explanation
Correct answer: Less light reaches the area where the object touches the surface.
A contact shadow forms at the immediate meeting point between an object and the supporting surface. Because the gap is extremely small or absent there, direct and reflected light are strongly blocked, so the area can appear darker and more compact than the broader cast shadow. Option A is correct because reduced light access explains the increased darkness. The wider cast shadow may become softer and lighter as it spreads away from the object and receives reflected light. Option B reverses the meaning of shadow, while options C and D have no physical or visual basis. The exact value still depends on light, material, and surrounding reflection.
