behaviors of sound and light: which three examples correctly demonstrate the behavior of sound and light? a person can hear a television playing in a closed room but cannot see it. a person behind a thick black curtain can see light but cannot hear people on the other side of the curtain. a cars headlights are visible to people before the car is close enough to hear. two people talking to each other need light to hear each other speak. a glass breaks in a restaurant, and people who do not see the glass can hear it break. a b c d e

Explanation:

• Option A: Sound can travel through walls (solid medium), while light is blocked (opaque door). This shows different behaviors.
• Option C: Light (from headlights) travels faster than sound. So light is visible before sound is heard.
• Option E: Sound (of breaking glass) can travel to people who don't see (light is blocked).
