Physics Questions

What concept related to light or vision is described in the riddle: “I move without legs, I rise without wings, you can hear my voice in silent things. I follow you in sunlight, but disappear at night, always present but out of sight. Without me, you can’t see, yet I’m no living being. What am I?” A. Light B. Shadow C. Darkness D. Reflection

Short Answer

The riddle describes a shadow, which is created when an object blocks light, resulting in a dark shape on a surface. Clues from the riddle highlight that shadows move without legs, are noticed silently, appear in sunlight, and have unique attributes like being always present yet often overlooked.

Step-by-Step Solution

Step 1: Understand the Concept of Shadows

The riddle describes a shadow, which is a phenomenon related to light. A shadow appears when an object blocks light, resulting in a dark shape on a surface. It can change position depending on the angle and intensity of the light source.

Step 2: Analyze the Riddle’s Clues

The riddle provides several clues to help identify what a shadow is. These clues include:

  • “I move without legs, I rise without wings”: Shadows shift without physical movement.
  • “You can hear my voice in silent things”: This suggests that shadows can be noticed without sound.
  • “I follow you in sunlight, but disappear at night”: Shadows are only visible in the presence of light, typically from the sun.

Step 3: Recognize the Characteristics of Shadows

Shadows have unique attributes that help us understand their nature:

  • “Always present but out of sight”: Shadows exist whenever there is light, though they might go unnoticed.
  • “Without me, you can’t see, yet I’m no living being”: Shadows provide contrast that aids visibility, but they are not alive themselves.
