It is a physical change
at least that is what I've been told
Color is a physical property.
No, the color purple is a physical property of an object that results from the absorption and reflection of certain wavelengths of light. It is not the result of a physical or chemical change, but rather the interaction of light with the object's molecules.
Radiation would be a chemical property. Remember, a physical property is something that does not change the composition or "identity" of a substance whereas a chemical property is something that does. Since anything exposed to radiation for a good amount of time would experience change in composition, it is thus referred to as a chemical property.
Fire is not a physical or chemical property. Fire is not a property. Fire is a chemical reaction where oxygen combines with some or all of the chemical components of the fuel, emitting light and heat.
Luster is a physical property, not a chemical change. Luster refers to the way light interacts with the surface of a material, causing it to either appear shiny or dull. It does not involve any alteration of the chemical composition of the material.
It is a chemical property, as it involves a chemical change.

It is a chemical property of matter. When a substance decomposes on exposure to ultraviolet light, it undergoes a chemical change in its molecular structure, leading to the breakdown of its components into different substances.
The formation of a silver metallic color on sodium metal is a physical change. This change is due to the reflection of light by the metal's surface, and the silver color is a property change and does not involve a change in the chemical composition of the sodium metal.
The luster of platinum jewelry is a physical property. Luster is a visual appearance attribute of the surface of a material, caused by the reflection of light. It is not a characteristic that involves a change in the chemical composition of the material.
The metallic silver appearance of sodium is a physical property because it relates to its visual appearance and how it interacts with light, rather than a chemical change in its composition.
