I would think it to be a Physical Change. Not chemical.
i think it would be physical because it is still energy.
It's not a change at all. It is simply what the firefly does. But it is a result of a chemical change within the firefly. A chemical reaction involves a transfer of energy. In this case, the energy would go into creating light waves from the molecules in the firefly, causing it to glow.
A beam of light becoming dimmer is a physical change since it is reversible. Recharging its source will make the light beam bright again.
Change in temperature, gaseous bubbles, giving off light, change in color, change in properties. These are chemical changes, but it is still five examples of science.
It's a physical change. A chemical change is when a new substance is formed. A physical change is when something looks, feels, tastes, or smells different, but it's the same substance. You see the firefly is always glowing, it's just the fact that the human eye cannot see it because it is being over powered by the light of the Sun; but it's still the same firefly.
Giving off light is considered a chemical change, not a physical change. This is because the emission of light usually involves chemical reactions at the atomic or molecular level that result in the production and release of photons.
This is both a physical and chemical change. The explosion involves the release of energy (heat and light), which is a chemical change due to the breaking of chemical bonds. The breaking of the wrapper into many pieces is a physical change as it does not involve any change in the chemical composition of the materials.

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.
Its a chemical change hottie

It would be physical change because the substance doesn't change. Signs of chemical changes would be absorbing, liberating (releasing) heat, fizzing, changes of color,or giving off light.
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 its a chemical change for it can't be reversed
Heat, light, and change in odor can indicate a physical change depending on the context. For example, melting ice into water is a physical change because it does not alter the chemical composition of the substance. However, if a substance undergoes a chemical reaction that results in heat, light, and change in odor, then it would be considered a chemical change.
