It is a physical change because nothing actually changes in the flashlight or surrounding areas. It's just electricity flowing and a light coming on and some heat produced.
The flash of a camera is a physical change, not a chemical change. A physical change is a change in the form of a substance without changing its chemical composition. In the case of a camera flash, electrical energy is converted into light energy, which is a physical process that does not alter the chemical makeup of the components involved.
No.
A light bulb is not a change in and of itself but the process by which it gives off light is physical. While an electric current causes a given component of the bulb to glow (it may be the filament of an incandescent bulb or the vapor in a fluorescent one), but that substance does not change its chemical identity.

turn the car to acessary or trun the car on with out turning the egine over and then hold the trip oil located by the by were it tell the millage on the car the change oil will then flash
Turning on a glow stick is a chemical change because the chemicals inside the stick react to produce light. This reaction cannot be easily reversed, unlike physical changes where the substance retains its original properties.
physical
No this is a myth and what dumb question
Yes, for example solar cells produce electricity (physical change) which can then be converted to light energy.
Most of the time the emission of light is a physical change but there are some chemical reactions which emit light as a byproduct of the reaction.
That's the point. So people behind you know you are turning.
