i think it would be physical because it is still energy.
I would think it to be a Physical Change. Not chemical.
A beam of light becoming dimmer is a physical change since it is reversible. Recharging its source will make the light beam bright again.
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.
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.
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.

Its a chemical change hottie
The production of light by a lamp is a physical change. It involves the conversion of electrical energy into light energy through a process that does not alter the chemical composition of the materials involved.
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.
The production of light can be a physical or chemical property. Physical properties would include phenomena like luminescence or fluorescence, where certain materials are capable of emitting light without undergoing chemical reactions. Chemical properties would include processes like combustion or bioluminescence, where the production of light is a result of chemical reactions taking place.
A change in state does not necessarily indicate a chemical change. Melting, freezing, boiling, or condensing of a substance are physical changes that do not involve a change in the chemical composition of the substance.

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 because it showain't chemical ...chemical does one of the three production of heat or light Production of gas or formation of precipitate which is a solid ... anonymous i don't know how ta spell dat a word tho
This would be defined as a physical change. In chemistry, this would be defined as anything from a change in mass or volume to a change in state (solid, liquid, gas). As long as the substance does not change in molecular structure, it is mostly a physical change. Common indicators of a chemical change is change in color, production of light, production of extensive heat, production of uncommon smells, or even bubbling.
Signs of a chemical change include the formation of a new substance, a change in color, production of gas or bubbles, release of heat or light, and a change in odor. These changes are not easily reversible and often involve the rearrangement of atoms.
