Item NG045002: Both a light bulb and an ice cream cone radiate energy because all objects radiate energy.

Consider a light bulb and an ice cream cone.

Which gives off energy by radiation and why?

  1. Both a light bulb and an ice cream cone because all objects radiate energy
  2. Neither a light bulb nor an ice cream cone because only the sun radiates energy
  3. Only a light bulb when it is glowing because only glowing objects radiate energy
