flashlight is always lighting for people in dark. There are other more applications from differrent color light, such as imalent flashlight, spot light is for daily use, UV light can check ID card or ticket, red light can be used warning in traffic.
A fire and a flashlight are able to add light to the dark to help people see objects.
it would be heat to light or chemical to electrical to light
it made them see if there was no light or electricity.
The cop shined his flashlight so that the beam of light hit the criminal's face.
The function of the bulb in a flashlight is to generate some light when some electrical current passes through it. Note: That's actually the whole purpose of the flashlight. If there were no part of it that generated any light, then you do just as well without the flashlight altogether.
Need clarification please. The "it" you are referring to seeing, does that represent; A) the flashlight, B) the light from the flashlight, or C) "the speed of light"? Did you mean to imply that the flashlight was switched on? Is it an "old fashioned" bulb, an LED bulb, a laser light, or some other energy? Just wondering.
A flashlight is a portable light source typically powered by batteries or electricity. When turned on, the flashlight emits a beam of light through the use of a light bulb or LED. This allows users to illuminate dark spaces or see in low light conditions.

Flashlight
Light travels from a flashlight to a solid through the process of reflection and absorption. When the light beam hits the solid surface, some of it is absorbed, and some is reflected. The absorbed light energy can cause the atoms in the solid to vibrate, generating heat.
A flashlight typically produces white light, which is a combination of all visible wavelengths of light. The light is usually emitted from a light bulb or LED located within the flashlight.
A flashlight transforms electrical energy into light energy and some heat energy. When the battery powers the flashlight, the electrical energy is converted into light energy when the bulb or LED emits light, while some of the energy is also lost as heat.
A flashlight has a power source (usually ordinary batteries), a light source of some sort (a light bulb or LED, for example), and some electrical wiring to connect them, with a switch to turn it on and off. The power source makes the light source give off light.
