Torch light is NOT a natural source of light. It is an Artificial Source of light generated by the electrical energy. In this the electrical energy is being transformed into Light energy.
No. A light bulb is.
Uranium is not artificial radioactivity so it is not clear what the question is about.

For example natural and artificial radioactivity.
"Natural light" typically refers to light that originates in the sun. "Artificial light" typically refers to light that originates in human-made devices.
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
Candlelight is man-made, so is artificial. Sunlight is natural light from the Sun.
Why are artificial lights bad for you? The reason. They are strictly not natural.
Definitely natural!
