A flash light generally makes light using a light bulb, which contains a filament. The filament is typically made from tungsten. It is very thin, but capable of withstanding extremely high temperatures. Electricity, from an internal power source, is passed through the filament. The filament has a resistance, so the current creates a very large heat in the wire. Because the wire is so thin, it heats up very quickly, and this excess energy is given out as light, and heat.
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.
Yes it is possible to make an acid battery using the acid in a lemon. (you would need allot of lemon batteries to light a flashlight bulb though - try using a diode light bulb) For more information on how to do this look in the link I will place below.
The distance light from a flashlight travels depends on the brightness of the light, atmospheric conditions, and any obstacles in its path. Typically, light from a flashlight can travel several hundred feet in the dark before becoming too dim to be visible.
Turn your flashlight on and off. The light wave begins and ends. The light wave from your flashlight will take 1 nanosecond to travel one foot from your flashlight.
No, when you turn on a flashlight, the emission of light does not exert a force on the flashlight itself. The light is simply released in the form of photons, which travel in straight lines until they interact with something else.
In a straight line. At the speed of light.
The speed of light from a flashlight is the speed of light, which is approximately 299,792 kilometers per second in a vacuum. When you turn on a flashlight, the light it emits will travel at this constant speed until it interacts with another medium.

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.
Sun light is more brighter than the light from flashlight in house.
