A torch uses reflection to direct and focus light emitted from its bulb. Inside the torch, a reflective material, often in the form of a parabolic reflector, surrounds the bulb. This reflector captures the light rays and directs them forward, creating a concentrated beam of light that illuminates a specific area. This design enhances the efficiency of the torch by maximizing the usable light output.
