Which describes incandescent light?

Explanation:
Incandescent light comes from heat. When a filament is heated to a high temperature, it glows and emits visible light as part of thermal radiation. The hotter it gets, the more light in the visible range is produced, not just heat. This is different from lights that shine because of chemical reactions or glow without heat, which is why the statement that describes incandescent light is: visible light is emitted when heated to a high temperature.
