What is the primary function of a torch?

The primary function of a torch is to illuminate dark areas. Torches typically use a light source, such as a bulb or LED, powered by batteries, to provide illumination in conditions where natural light is insufficient. This makes them indispensable for activities such as camping, hiking, and emergency situations where seeing in the dark is crucial. The design and function of a torch make it a portable and convenient source of light, allowing individuals to explore dark spaces safely and effectively.

The other functions mentioned, such as marking locations, measuring temperature, or navigating through space, do not align with the core purpose of a torch. While some tools may integrate these features, the fundamental purpose of a torch remains focused on providing light.
