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.
It is a physical change at least that is what I've been told

A beam of light becoming dimmer is a physical change since it is reversible. Recharging its source will make the light beam bright again.
Both !
This is a physical change. When the electrons go through the filament (or gas), there is no chemical change, only the physical change of temperature. The electricity to power the light may be generated chemically (fossil fuels or batteries) or from a hydroelectric plant. The light from "glow sticks" is an example of light generated by chemical changes.
Its a chemical change hottie
