Answer 21

Hmm..The metal wire in an incandescent lightbulb glows when the light is switched on and stops glowing when it is switched off. This simple process which takes placethrough chemical reactions in a process called bioluminescence

Answer 22

And so i suggest chemical change... not physical as no change in bulbs coil takes place,and not ionic as ionic changes produce no light.

Answer 31

@Cuanchi \(Good~Question~!\) Well, does burning of film, when a bulb glows shows any physical change to its surrounding glass or the film ? film glows bcuz of heat but doesn't change the film or its shape. but when you refer luminescence you find the real change.
