Final answer:
An artificial light source example is a lightbulb, specifically an incandescent light bulb, which illuminates by heating a filament. Other artificial sources include LED and fluorescent lights that emit light when an electrical current passes through.
Step-by-step explanation:
An example of an artificial light source is a lightbulb. Unlike natural light sources like the Sun, an artificial light source is one created by humans for illumination. The incandescent light bulb, commonly found in households, generates light by heating a filament inside the bulb until it glows. This process is a way to produce light by heating an object, as seen with incandescent lights. Alternatively, sources like fluorescent and LED lights operate by passing an electrical current through matter, causing the material to emit light.
