Yes it is for eample a burning stick
Water is not a scource of light.
the scource is most likely the water but you should check the internet. Good Luck homy-G!!
bread

In electricity yes.
When you break a light stick, it is a physical change, not a chemical change. The breaking of the light stick only changes its physical state but does not alter its chemical composition. This is because the chemical reactions that produce light in a light stick have already occurred when the stick was activated, and breaking it does not initiate any new chemical reactions.

no, well depends on what your looking up! =-) xx
Yes, a glow stick produces light by means of a chemical change.
In a light stick, the energy transfer involves converting chemical energy into light energy. A chemical reaction inside the light stick produces light without generating heat, making it a safe and efficient source of illumination.
Light emitted from a glow stick can be measured using a light meter that quantifies the intensity of the emitted light. The unit of measurement for light intensity is typically in lux or lumens. By placing the light meter close to the glow stick, you can determine the brightness of the light it produces.
