Answer 2

Thomas Edison improved the light bulb by creating a long-lasting and practical version using a carbonized bamboo filament, which could burn for over 1200 hours. He also developed a better vacuum pump to remove air from the bulb, resulting in a longer lifespan for the filament. Additionally, Edison worked on various materials for the filament, eventually settling on a carbonized cotton thread that further extended the light bulb's durability.
