Final answer:
The statement is true; light bulbs convert electrical energy into both light energy and heat energy, which can be observed in incandescent bulbs and more energy-efficient CFLs.
Step-by-step explanation:
The statement that a light bulb can show two types of energy is true. Light bulbs convert electrical energy into both light energy and heat energy. Incandescent light bulbs, such as a 25-W bulb and a 60-W bulb, mainly emit visible light and infrared radiation due to the heating of the tungsten filament.
Compact fluorescent light bulbs (CFLs), on the other hand, are designed to be more energy-efficient, giving off the same light intensity as higher wattage incandescent bulbs but with significantly less energy consumption. However, they still emit light and some heat energy, though usually less heat than their incandescent counterparts.
