The term "incandescent" refers to something that emits light as a result of being heated. This phenomenon is commonly seen in traditional light bulbs, where a thin filament made of tungsten glows brightly when an electric current passes through it. The heat generated causes the filament to reach a high temperature, producing visible light. In a broader sense, "incandescent" can also describe anything that shines brightly or radiates warmth and passion. For example, an incandescent personality might be someone who exudes energy and enthusiasm, captivating those around them with their vibrant presence.
